what is the use of def in python
Some times you need a function that's not included in python , so you can create your own function with (def) and use it as much as you want by calling it.. Ex. def my_func(): print("My own function") my_func() >>> 'My own function' >>>
Def indicates you are defining your own function (also known as a method). What a function is is simply a piece of code you can use over and over and over. If I were to say: Def MyFunc(args): print(args) MyFunc(5) This would print out the number 5. I am sending the argument of 5 as the variable 'args' and printing it out in the function's code.
It is used if you want to run a code multiple times in your program but you don't want to repeat it many times thus saving space and making your code more readable and less complicated. example: def print_i(): print("Hi") print_i() print("Hello") print_i() Result: Hi Hello Hi
