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 The creation of the function module of .
stay Python in , Every Python Files can be used as a module , The name of the module is the file name .
for example ： There is a file “test.py”, It defines the function to find the smaller value minimal().
def minimal(x, y): # Custom calculate small value function
if x > y: # If x>y establish , return y Value
return y
else: # Otherwise return to x Value
return x
example ： Programming , By calling “test” Module minimal() function , Calculate the smaller of two numbers .
import test # Import test modular
a = float(input(' Enter the first data ：')) # Input a Value
b = float(input(' Enter the second data ：')) # Input b Value
c = test.minimal(a, b) # Call function , Assign a smaller value to c
print(' The smaller value is ：',c) # Output c Value
give the result as follows .
In the actual development process , In order to make the module achieve the desired effect in the project , Will add test information to the module by itself .
for example ： stay “test_1.py” Add the following test code to the file ：
import test_1 # Import test_1 modular
c = test_1.minimal(5,6) # Call function , Assign a smaller value to c
print(' The smaller value is ：',c) # Output smaller values c
def minimal(x, y): # Custom calculate small value function
if x > y: # If x>y establish , return y Value
return y
else: # Otherwise return to x Value
return x
# For testing
r = minimal(2,3)
print(' test 2 and 3 The smaller value of is :',r)
example ： Run the following program , Analyze the running results .

The above is about Python Knowledge about the creation of function modules , You can refer to it , If you think it's good , Welcome to thumb up 、 Collection 、 Looking at , Welcome to wechat search java Basic notes , Relevant knowledge will be continuously updated later , Make progress together .
