Python String .isdigit() method.

Let's Apply it on any string, and it'll return a boolean of true or false.

			
					str = "1234";
print(str.isdigit()) # True

remove numbers from String

Now, we run with a string of numbers that will return true.

			
					str = "isStr123";
print(str.isdigit()) # False

If the given string input is a mix of numbers and letters, it's going to return false.

.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 .join() method.

String. join() method to remove the numbers from the String.
