Remove first n characters from a string

In Python, you can remove the first 'n' characters from a string by using slicing. The slice notation [n:] can be used to select all characters in a string starting from the nth index.

Using Python slicing

Here is an example of how you can use Python slicing to remove the first 2 characters from a string:
original_string = "Hello, World!" new_string = original_string[2:] print(new_string)
// Output: "llo, World!"

Using negative indexing

You can also use negative indexing to remove characters from the end of the string.
original_string = "Hello, World!" new_string = original_string[:-2] print(new_string)
// Output: "Hello, Wor"

Using string.lstrip() method

You can also use string.lstrip() method to remove specific characters from the left side of the string.
original_string = "Hello, World!" new_string = original_string.lstrip("H") print(new_string)
// Output: "ello, World!"
Note that this method only removes characters from the left side of the string, if you need to remove from both side use string.strip() method.
original_string = "Hello, World!" new_string = original_string.strip("H!") print(new_string)
// Output: "ello, World"

Using string.replace() method


Python replace
You can also use the string.replace() method to remove specific characters from a string.
original_string = "Hello, World!" new_string = original_string.replace("H","") print(new_string)
// Output: "ello, World!"
These are some examples of how you can remove the first n characters from a string in Python. Depending on your use case, one of these methods may be more appropriate than the others.
