We used the str() class to convert the number to a string. This is necessary because adding leading zeros to a number causes a SyntaxError. The str.zfill() method takes the width of the string and left-fills the string with 0 digits to make it of the specified width. main.py Copied...

In these examples, you use different precision values to display the output number. The precision is separated from the width by a literal dot (.). For string representation types, precision specifies the maximum width of the output: Python 👇 >>> f"{'Pythonista':.6s}" 'Python' 👇...
