Today we are embarking on: Remove Character from String in Python by Index. To remove a specific character from a string given a specified index, the easiest way is with string slicing. This is a common scenario that many users run into.
Why Remove a Character from a String?
Manipulating and modifying the values of variables, especially when dealing with strings, is a fundamental aspect of programming. The ability to efficiently alter string content is invaluable in various scenarios. One common need arises when you want to eliminate a specific character from a string at a specified position in Python.
string = "example string"
def remove_char_by_index(s, idx):
return s[:idx-1] + s[idx:]
print(remove_char_by_index(string,4))
#Output:

One such case is if you want to remove a specific character from a string by specified position in Python.
To remove a character from a string by index in Python, the easiest way is with string slicing.
First, you create a slice from the beginning up to the index minus 1 and then create a second slice from the index to the end of the string. Then, you concatenate those two slices to get back a string with the desired character removed.
Below is a simple example of how you can remove a character from a string by index using Python.
string = "example string"
def remove_char_by_index(s, idx):
return s[:idx-1] + s[idx:]
print(remove_char_by_index(string,4))
#Output:
