Python String .isdigit() method.
- Let’s Apply it on any string, and it’ll return a boolean of
str = "1234"; print(str.isdigit()) # True
remove numbers from String
- Now, we run with a string of numbers that will return
str = "isStr123"; print(str.isdigit()) # False
- If the given string input is a mix of numbers and letters, it’s going to return
.isdigit()needs to all numbers to work.
- If the given String is decimals like, say,
0.1, that’s not going to work.
str = "0.1234"; print(str.isdigit()) # False
arr = "Hello1234" print([i for i in arr if not i.isdigit()]) # ['H', 'e', 'l', 'l', 'o']
- The Above Code eliminates all the numbers. Now let’s join together with the
String. join() method to remove the numbers from the String.
