Conditional expressions, involving keywords such as if, elif, and else, provide Python programs ability to perform different actions depending on a boolean condition: True or False. Conditional imports are somewhat common in code that supports multiple platforms, or code that supports additional functionality when some extra bonus modules are available. It can be done using the ternary/binary If operators in vb.net and their equivalent operators, the conditional operator ? It is the decision making the statement in Python programming works on the basis of conditions. Do you know that you can write a nested conditional statement in .net with true and false sides in a single line of code?
