capitalize

Capitalizes the first letter of a string.

Capitalizes the first letter of the string and then adds it with rest of the string. Omit the lower_rest parameter to keep the rest of the string intact, or set it to true to convert to lowercase.

def capitalize(string, lower_rest=False):
    return string[:1].upper() + (string[1:].lower() if lower_rest else string[1:])

capitalize('fooBar') # 'FooBar'
capitalize('fooBar', True) # 'Foobar'
