How to Compare Strings Using Python

How to Compare Strings Using Python

Do you know how to compare strings Python? Have you ever thought what are the possible methods to compare strings in Python? Let us gain knowledge about the methods to compare strings Python.

But before we start writing about the methods to compare strings Python. We must try to think why we need to compare strings Python. Then we will approach how to compare strings in Python.

Let us try to assume one scenario.

Suppose, we went to your bank. There you need to withdraw some amount from your bank account. And you don’t have the cheque option to withdraw the desired amount. So, you used one withdrawal slip from the bank. You filled up your details & other necessary information. When your turn comes up at the cash counter, the authority denied you to provide the amount.

Why did that happen to you?

They informed you that, you have put the wrong account number there. That is the reason, they can’t able to provide you with the amount. So now, you have to again fill up the new slip. You might find it a usual case. But there is a large comparison processing behind the screen.

This is the basic implementation of this topic. Compare strings Python helps to compare two or more strings. Like in the above example, the original account number doesn’t match your provided account number. So the withdrawal process stopped. If the comparison doesn’t happen at that time, the account-related problem arises.

What Are Strings In Python? Read Below

 

Strings are the set of characters in Python programming language. Just like, an array is used as a set of numbers or integers. The strings are used as the set of characters. Every statement can be used as a string. Every word including space can be used inside of a string. A string is known as the character array.

Like an array, there is also an index in the strings. A number can also be used inside the string. So, the numbers or digits will work as the character inside of the strings. We can use uppercase & lowercase characters there inside of a string. Special characters are also allowed there. We can use the underscore, space, etc. Each of them will act as a character there. They will occupy one index of the character array.

Strings play an important role. In our daily life, we used many strings. Like the name, location, etc. These all are one type of string. In various other programming languages, we need to store some string data. So, for that, a special field was promoted to them. Using string, one can compare them. It will help to distinguish the list of strings.

 

What Are The Methods To Compare Strings Python? Get To Know

 

Now, it is time to answer how to compare strings in Python. For that purpose, there are two ways. In one case, we need to use relational operators. We all know about relational operators. This is mainly used in the numerical comparison. And in another case, we can use the inbuild function of the Python programming language.

Let us make a list of ways to compare strings in Python:

  1. Using Relational Operator
  2. Using is Method

The above methods will help to compare strings in Python. Let us know about each & every method one by one briefly. It will help to understand the topic in a better way.

 

Compare Strings Python Using Relational Operator:

 

Relational operators are mainly used in the numerical fields of programming languages. We often used this method to compare two or more integers. There are some operators like Equal To (= =) Operator, Not Equal To (!=) Operator, Greater Than Equal To (< =) Operator, etc. Among them, here we are going to use two operators. Though there is also a way to implement the other operators. But in most cases, two operators can be used.

We will use Equal To (= =) Operator first. This operator will compare strings in Python. If two strings are the same, it will return the Boolean value True. If two strings are not equal to each other, it will return the Boolean value False.

Here, first, we have taken two strings. We have declared those strings. Now we will use the Equal To operator. As those two strings are not equal to each other, it will return the False value first. In the second print() method, we have used Not Equal To Operator. As those strings are not equal to each other, it will return the True value.

 

Example:

 

# Declaring The Strings

str1 = "CodingZap"

str2 = "ZapOne"

print("Are They Same: ",str1 == str2) # Using Relational Operator

print("Means They Are Not Equal: ",str1 != str2) # Using Not Equal To Sign

 

Let us look at the output of the above code. It will help to understand the method to compare strings Python.

 

Output:

 

Compare Strings Python Using Relational Operator Output

 

Compare Strings Python Using is Method:

 

There is a special method in Python programming language. This is known as the is the method. This method can be used as a replacement for the Equal To (= =) operator. This method compares two strings. If they are equal to each other, it will return the True value. If the strings are not equal to each other, it will return the False value.

Here, we have taken two different strings. Now, we will print the return value after comparing the strings. As they are different strings, it will provide the output False.

 

Example:

 

# Declaring The Strings

str1 = "CodingZap"

str2 = "ZapOne"

print("Comparing Between Str1 & Str2, Result: : ",str1 is str2) # Using The is Method

 

Let us look at the output of the above code. It will help to understand the method to compare strings Python.

 

Output:

Compare Strings Python Using is Method Output

 

Conclusion:

 

As we saw compare strings Python is a very important topic.

We always remember how to compare strings in Python section. It will help further in the future.

We need to first clear the basics of the Python programming language. It is always advisable to clear the basic concept before moving to this topic.
