Here is a Python function to turn first char to lowercase

import pandas as pd

def first_char_to_lower(s):
    """
    Turn first char to lowercase
    """
    return s[0].lower() + s[1:]

# Enter the string
s = "Hello World"

# Calling the function
print((first_char_to_lower(s)))

#Example Output
# hello World

#Remember to inspect code for bugs.
