# Function return value

Max_num =

If B> max_num:

Max_num = B

If C> max_num:

Max_num = C

# Function return value:

The parameter enters the function. After some business logic processing, the processed result is returned.

# The return value starts with return. It can return numbers, strings, and boolean values.

# Generally, the return value of a function is clearly defined. The calculation logic should be separated from the business logic.

# It is recommended that clear values be returned. If a function with a return value is disabled, none is returned by default.

# Easy to error: the function does not contain print (). After the function is called, the terminal cannot see the result because the terminal accepts and prints the return value of the function.

 

#2. functions that do not need to return values, but encapsulation of some functions

 

Def maday ():

Print ('upgrade ')

Print ('eat breakfast ')

Print ('workday ')

Print ('sleep ')

Print ('doubean ')

 

#3. functions that return multiple values

Def get_max_min (A, B, C ):

Max_num =
Max_min =

If B> max_num:
Max_num = B
If C> max_num:
Max_num = C

If B <max_min:
Max_min = B
If C <max_min:
Max_min = C

Return max_num, max_min

Num1, num2 = get_max_min (1, 5, 3)
Print ('maximum {}, minimum '. Format (num1, num2 ))

# A function can have multiple return values separated by commas (,) during return.
# Destructor assignment and unpackage assignment: the number of values returned by the function is accepted by the number of variables in the same order.
