String Equals Check in Python: Using 4 Different Methods

In programming, string comparison is a fundamental operation used to determine whether two strings are equal.

Suppose you are building an application where you want to find a user using his/her username, the username stored in the database is a string and the keyword to be searched is also a string. So you would have to implement some functionality to detect that both strings are the same. Here comes the string comparison.

In this tutorial, we will learn how to compare strings using four different methods so you can choose any one as per your requirement.

Python String Comparison

In Python, string comparison is basically a process through which we compare the strings character-by-character to check for equality.

We can compare strings using several ways like using ‘==’ operator, ‘!=’ operator, ‘is’ operator and __eq__() function. Let’s look at them one by one.

Python ‘==’ Operator to Check the Equality of Two Strings

Python Comparison operators can be used to compare strings and check for their equality in a case-sensitive manner i.e. uppercase letters and lowercase letters would be treated differently.

Python ‘==’ operator compares the two strings in a character-by-character manner and returns True if both strings are equal, otherwise, it returns False.

Syntax:

string1 == string2

Example:

s1 = "Python"
s2 = "Python"
s3 = "Java"

print(s1 == s2)
print(s1 == s3)

Output:

True
False
