To create a loop that iterates over a list.

To execute code conditionally based on a boolean expression.

To define a function in Python.

To import modules into a Python script.

The main difference is that 'while' loops are condition-driven and can run indefinitely, while 'for' loops are count-driven and iterate a specific number of times.

'While' loops are used for iterating over arrays only.

'While' loops require a counter variable to function properly.

'For' loops can run indefinitely while 'while' loops have a fixed number of iterations.

A list can only contain integers, while a tuple can contain any data type.

Both lists and tuples are mutable and can be changed.

A list is mutable and can be changed, while a tuple is immutable and cannot be changed.

A list is immutable and cannot be changed, while a tuple is mutable and can be changed.

Ignore exceptions and continue execution.

Use if-else statements to handle exceptions.

Use try-except blocks to handle exceptions.

Log exceptions without handling them.

a) Using the concat() method

b) Using the join() method

c) Using the & operator

d) Using the + operato

a) toupper()

b) uppercase()
