1. The problem of indentation
2. The global and local variables need to know about the knowledge

CodePudding user response:

On the second floor right
1, the indentation you have one more tabs
2, your function is can't find the num of the variable, you want inside the function definition num
A simple for loop is

 
Def func (n) : 
Num=0 
For I in range (n + 1) : 
Num=num + I 
Print (num) 

Func (100) 

CodePudding user response:

Inside the function add
Global num

CodePudding user response:

 def func (n) : 
If n==0: 
Return 0 
The else: 
Return the n + func (n - 1) 

Print (func (10)) 

CodePudding user response:

You have to make clear the scope of the function variables, function outside the num of variable and function inside the num is different

CodePudding user response:

Such use variables, is not a good habit
