BPP (313011) Practical No.10: Create python program to demonstrate use of math built-in function
Python includes multiple math-related and string-related functions. The math built-in module is used to perform various mathematical calculations, such as numeric, trigonometric, logarithmic, and exponential calculations. The Python string module provides several constants that are useful for checking to see if a character, slice, or string contains letters, digits, symbols, etc. To use these modules, we need to import the module into our code.
