In practically any programming language, one of the most important tasks for Python programmers is string comparison. The most common use of string comparison is to discover duplicates in database software. In the domain of programming, string has its own significance.

In this blog, we’ll look at how to compare strings in Python. It will assist you in determining the finest and most basic method for comparing strings in Python.

But, before we go into the string cmp in Python blog, it’s important to understand what string is and how it works in Python programming. After we’ve mastered the fundamentals of strings, we’ll move on to learning how to compare strings in Python using various operators.

Don’t worry, we’ll provide you the best example possible, complete with outputs, to eliminate all of your doubts. Let’s get started learning how to compare strings in Python:-

In Python, how do you compare two strings that are equal?

In Python, you can easily compare two strings to see if they are equal by using the (==) operator. Aside from that, you can use the (!=) operator to check for inequality between two strings.

In Python, how do I see if two strings are equal?

The (==) operator is the best technique to see if two strings are equal in Python. Aside from that, the __eq__() function can be used. Because Python is a case-sensitive language, you must ensure that the strings’ cases are equivalent before comparing them.

Does Python’s == work with strings?

Yes, Python strings == works. It works with practically all Python objects, including strings, lists, dicts, and functions. Consider the following example: if an is b, then a==b is true, but not always.

In Python, how do you check if a string is equal to another string?

The “==” operator is the most straightforward way to check it. With the aid of this operator, it is simple to compare strings character by character. Its mechanism is straightforward: it returns true if the two strings are equal or equivalent, and false otherwise.

What exactly are strings?

A sequence of characters is called a string. An alphabet, symbol, or number can be used as a character. And binary code is used to represent all of these characters in the computer. Each character, integer, and symbol has its own binary code. All of them are encoded in binary code and then decoded as the final output to the users.

Aside from that, we may argue that every character that users see on their screens is a string. It’s important to remember that there are two types of encoding techniques: ASCII and Unicode. Unicode is now supported by the majority of programming languages, including Python. Let’s get back to our main topic, Python string comparison.

Python Comparison of Strings

Python Relational Operators for String Comparison

Python has a number of operators that may be used to compare strings and determine whether they are equivalent. It can also assist us in comparing the lesser and larger stings. These operators always produce true or false boolean values and compare them using their Unicode values. Let’s have a look at these operators in more detail.

The “==” operator is used to determine whether two strings are equal. It is one of the most commonly used operators in Python for comparing strings. Let’s look at an example of python string comparison:-

s1 equals ‘Python’

s2 equals ‘Python’

if s1 equals s2:

print(‘s1 and s2 have the same value’)

else:

print(‘s1 and s2 don’t match’)

Output

s1 and s2 are the same.

The “!=” operation is used to ensure that both strings are not equal. It has the opposite effect as the “==” operator. Let’s look at an example of python string comparison:-

Output

s1 and s2 aren’t the same.

The “” operator is used to ensure that the left-hand string is smaller than the right-hand string. Let’s look at an example of python string comparison:-

Output

s1 is smaller than s2.

The “=” operator is used to ensure that the left-hand spring is smaller or equal to the right-hand string. Any of these two conditions should be met with this operator. Let’s look at an example of python string comparison:-

Output

s1 is not the same as s2.

The “>” operator is used to ensure that the left-hand string is greater than the right-hand string. Let’s look at an example of python string comparison: -Output

s1 is more than s2.

The “>=” operator is used to see if the left-hand string is greater than or equal to the right-hand string. Any of the conditions should be met with this operator.

Output

s1 exceeds s2 in magnitude.

Remember that we almost always use the “==” operator to determine whether two strings are equal.

Python String Comparison with the “is” Operator

Consider the following example of using the “is” operator to compare strings. The “is” operator checks whether two strings are equal, as the name implies.

It returns True or false depending on the outcomes of the comparison, just like any other comparison operator. Similarly, if the strings are identical, it will return True, otherwise False. It has a simple syntax.

String1 corresponds to String2.

Let’s look at an example of python string comparison:-

As an example

string1=”Python”

string2=”Python”

If (string1 = string2), then

string1 = string2″ print(“string1 = string2”)

else:

print(“string1 and string2 are not equivalent”)

Output

string1 and string2 are the same.

Python’s “not is” operator is used to compare strings.

The is not operator looks a lot like the!= operator. If the strings are identical, True is returned; otherwise, False is returned. Consider the following syntax:-

String1 isn’t the same as String2.

Let’s look at an example of python string comparison:-

Example

“Python” as string1

string2=”Python”

create (string1 is not string2)

else:

create (string1 is equal to string 2)

Output

False

Python’s __eq__() method is used to compare strings.

Python is a programming language with many uses. It includes numerous functions that can assist you with a variety of activities. Using __eq__ to compare strings in Python is simple (). Any additional comparison operators and functions are the same.

It also compares the strings and returns True if they are identical, and False otherwise. Let’s look at an example of python string comparison:-

Syntax

str1. eq (str2)

Example

string1=”Python”

string2=”Python”

if(string1. eq (string2)):

string1 = string2″ print(“string1 = string2”)

else:

print(“string1 and string2 are not equivalent”)

Output

String 1 is the same as String 2.

It’s worth noting that the __eq__() function is case sensitive. This means that if you use this function to compare Python to Python, it will return False.

3. Using the sorted() function to compare two strings

Python has a variety of functions for comparing strings. It compares the string for equality even if the character/words are different. To compare two strings, we must utilize the sorted() method. Let’s look at an example of python string comparison:-

input = string1

(“Type your first word: “)

input(“Enter the second word: “) string2

If sorted(string1) and sorted(string2) are equal:

(“The first and second words are the same.”)

else:

(“The first and second words are different.”)

Output

Start with the first string: Programming in Python

Put the second string here: Python programming

The first and second strings are the same length.

Using the Case-Insensitive function in Python to compare strings

Now we’re utilizing the casefold() method in Python to compare strings. It enables us to compare strings that have various cases but the same character set. The reason for this is that it converts the string to lowercase automatically before comparing it. Let’s look at an example of python string comparison:-

s1 equals ‘Python’

s2 equals ‘python’

if s1.casefold() is equal to s2.casefold():

print(s1.casefold())

print(s2.casefold())

print(‘s1 and s2 have the same value’)

Output

python

python

s1 and s2 are the same.

Lower()

Lower() is a function that lowercases a string. The string can then be compared in lowercase. Let’s look at an example of python string comparison:-

s1 equals ‘Python’

s2 equals ‘python’

If s1.lower() equals s2.lower(), then

print(s1.lower())

print(s2.lower())

print(‘s1 and s2 have the same value’)

Output

python

python

s1 and s2 are the same.

Upper()

The higher() function raises the case of the string. The string can then be compared as uppercase. Let’s look at an example of python string comparison:-

s1 equals ‘Python’

s2 equals ‘python’

if s1.upper() and s2.upper() are equal:

print(s1.upper())

print(s3.upper())

print(‘s1 and s2 have the same value’)

Output

PYTHON

PYTHON

s1 and s2 are the same.

User Defined Function for Python String Comparison

We compare string Python utilizing user provided functions in addition to the built-in functions. We can compare the string on some parameters using these user created functions. Let’s look at an example of a user-defined Python string comparison.

comp str(string1, string2): define

c1 equals 0

c2 equals 0

in range(len(string1)) for I

if string1[i] is more than “0” and less than “6”:

1 + c2

in range(len(string2)) for I

if string2[i] is more than “0” and less than “6”:

1 + c2

c1 == c2 return

(comp str(“12345,” “Python”)

print(‘False’)

Python (comp str(“Python”, “Python”))

print(‘True’)

Output

False

True
