Question

like when to use it?

Answer 1

def main defines a function called main that you can then use in your script.

def main():
print("Hello world!")
main()

Answer 2

It is used for reusing code. With that you can take less time to make something multiple times. For example:
def main():
print ("Example")
#And then only you need to put main() instead of print("Example") multiple times

Answer 3

def in simply mean is assigning a definition to var e.g

def main():
print ("text")
