One 、 background

In the actual development process , You will often encounter many identical or very similar operations , At this time , Code that implements similar operations can be encapsulated as functions , Then call the function where you need it . This can not only realize code reuse , It can also make the code more organized , Increase code reliability . Now let's introduce python Function nesting definitions for .


Two 、 Nesting definition

Python Allow nested definitions of functions , That is, another function can be defined inside the function .
for example : The following code is in print_line() Functions are nested to define print_text() function .

def print_line(): # Definition print_line() function 
print("************")
def print_text(): # Nesting definition print_text() function 
print("Hello world!")
print_text() # call print_text() function 
print_line() # call print_line() function 

give the result as follows .
