What is the purpose of loops in Python?

Explain the difference between 'for' and 'while' loops in Python.

• The 'for' loop is used for executing a block of code repeatedly as long as a specified condition is true, while the 'while' loop is used for iterating over a sequence (like a list, tuple, string, etc.) or a range of numbers.

• The 'for' loop is used for iterating over a sequence (like a list, tuple, string, etc.) or a range of numbers, while the 'while' loop is used for executing a block of code repeatedly as long as a specified condition is true.
