Python: Remove the nth index character from a nonempty string

Last update on June 12 2025 12:43:18 (UTC/GMT +8 hours)

Remove nth character from a string.

Write a Python program to remove the n^th index character from a nonempty string.

Sample Solution:

Python Code:

# Define a function named remove_char that takes two arguments, 'str' and 'n'.
def remove_char(str, n):
    # Create a new string 'first_part' that includes all characters from the beginning of 'str' up to the character at index 'n' (not inclusive).
    first_part = str[:n]

    # Create a new string 'last_part' that includes all characters from the character at index 'n+1' to the end of 'str'.
    last_part = str[n+1:]

    # Return the result by concatenating 'first_part' and 'last_part', effectively removing the character at index 'n'.
    return first_part + last_part

# Call the remove_char function with different input strings and character positions and print the results.
print(remove_char('Python', 0))  # Output: 'ython'
print(remove_char('Python', 3))  # Output: 'Pyton'
print(remove_char('Python', 5))  # Output: 'Pytho'

Sample Output:

ython                                                                                                         
Pyton                                                                                                         
Pytho
