There is a function to capitalize a string, I would like to be able to change the first character of a string to be sure it will be lowercase.
How can I do that in Python?

To capitalize the first letter of a string and lowercase the rest, use the charAt() method to access the character at index 0 and capitalize it using the toUpperCase() method. Then concatenate the result with using the slice() method to to lowercase the rest of the string.
To convert the first letter of a string to lowercase, you can use string slicing and the Python lower() function. First, we get the first letter of a string and then use the lower() function to make it lowercase.
To capitalize the first character of a string, We can use the charAt() to separate the first character and then use the toUpperCase() function to capitalize it.
The toLowerCase method converts a string to lowercase letters. The toLowerCase() method doesn't take in any parameters. Strings in JavaScript are immutable. The toLowerCase() method converts the string specified into a new one that consists of only lowercase letters and returns that value.
One-liner which handles empty strings and None:
func = lambda s: s[:1].lower() + s[1:] if s else '' >>> func(None) >>> '' >>> func('') >>> '' >>> func('MARTINEAU') >>> 'mARTINEAU' If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
