Don't use the strip method without knowing this

Hello Pythonistas!

Today I will discuss an issue caused in my project and how I fixed this. We know that we have a strip method in the python string objects. When we use this method our expectation will be to remove the given sequence from the string, But actually strip remove the set of characters from the given series. I will explain this with an example

Code

a = "abc.com"
b = a.strip(".com")
print(b)

Expected Result

abc

Actual Result

ab

Why

The python documentation about strings specifies that the strip removes all the occurrences of the given set of characters. You can refer to the documentation here

Solution for this issue

If you are using python3.9 and above we have two methods removeprefix and removesuffix.

Code

a = "abc.com"
b = a.removeprefix(".com")
print(b)

Output

abc

If you are using the below that use the string slicing method or replace method

b = a[:-4]
c = a.replace(".com", "")
