To round a float to “2” decimals, the “round()”, “math.ceil()”, “format()”, and “f-string” methods along with the “decimal” module are utilized in Python.

To print integer values, the “print()” function, “f-string” method, and “sys.stdout.write()” function of the “sys” module are used in Python.

The “simple division and multiplication operator” or the “user-defined function” are used in Python to calculate the percentage.

The “TypeError: expected string or bytes-like object” arises when we pass various data type values to a method that expects string type parameter value.

The “TypeError: tuple object does not support item assignment” occurs when the user tries to change the element/items value of a tuple in Python.
