What is if name == Main in Python?
We can use an if __name__ == “__main__” block to allow or prevent parts of code from being run when the modules are imported. When the Python interpreter reads a file, the __name__ variable is set as __main__ if the module being run, or as the module’s name if it is imported.
How do you check condition in Python?
If-else conditional statement is used in Python when a situation leads to two conditions and one of them should hold true.
- Syntax: if (condition): code1 else: code2 [on_true] if [expression] else [on_false]
- Note: For more information, refer to Decision Making in Python (if , if..else, Nested if, if-elif)
What is condition statement in Python?
Decision-making in a programming language is automated using conditional statements, in which Python evaluates the code to see if it meets the specified conditions. The conditions are evaluated and processed as true or false. If this is found to be true, the program is run as needed.
What are the two main types of conditional statements in Python?
We have different types of conditional statements like if, if-else, elif, nested if, and nested if-else statements which control the execution of our program.
What is __ main __ in Python?
In Python, the special name __main__ is used for two important constructs: the name of the top-level environment of the program, which can be checked using the __name__ == ‘__main__’ expression; and. the __main__.py file in Python packages.
What Does main () do in Python?
The main function in Python acts as the point of execution for any program. Defining the main function in Python programming is a necessity to start the execution of the program as it gets executed only when the program is run directly and not executed when imported as a module.
What are conditional statements in programming?
Conditionals Statements – A way for computers to make decisions based on conditions. If/Else – A common form of conditional statements in programming; tells the computer that if the condition is true, do this. Else, if the condition is false, do another thing.

What is the main function?
The main function serves as the starting point for program execution. It usually controls program execution by directing the calls to other functions in the program. A program usually stops executing at the end of main, although it can terminate at other points in the program for a variety of reasons.
What is the use of conditional statement?
Conditional statements are used through the various programming languages to instruct the computer on the decision to make when given some conditions. These decisions are made if and only if the pre-stated conditions are either true or false , depending on the functions the programmer has in mind.
What is a conditional statement in Python give an example?
In conditional if Statement the additional block of code is merged as else statement which is performed when if condition is false. Syntax: if (condition): # Executes this block if # condition is true else: # Executes this block if # condition is false. Flow Chart:- Example 1: Python3.

What are the conditions for IF statements in Python?
Python Conditions and If statements. Python supports the usual logical conditions from mathematics: Equals: a == b. Not Equals: a != b. Less than: a < b. Less than or equal to: a <= b. Greater than: a > b. Greater than or equal to: a >= b. These conditions can be used in several ways, most commonly in “if statements” and loops.
