It is believed that many inexperienced people have no idea about how to use the Modules module in python. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

First, create a custom moudle file named my_module.py in the python file, and write the module code in this file:

Print ('Import Custom moudle Module')

Def find_index (search_list,target): "" find the index corresponding to target in the list "for iMagazine value in enumerate (search_list): if value = = target: return i return-1"

Create a new python file named py3_module.py file, and import the custom module for operation (note that the two files should be in the same directory):

# Import custom modules. Here, the name of the file is written in the import. # pay attention to the case where multiple paths are included. Import my_moudle.

Courses = ['Mathematics', 'Chinese', 'English', 'computer'] # call the function in the module # find the index index = my_moudle.find_index (courses,' computer) print (index) # some custom moudle modules have long names # you can use as aliases # you can write your own tests: # import my_moudle as mm#index = mm.find_index (courses) 'computer') # another import method # from my_moudle import find_index#index = find_index (courses,' computer) # is not recommended # if the current file also contains a function of the same name # it is easy to confuse # you can also alias the imported function using # from my_moudle import find_index as fi##index = fi (courses 'computer') # Import everything in the module # from my_moudle import * # then import the module of the built-in system import sys# to print the installation path of python# on my computer Module path information, such as print (sys.path) # python system adds path # sys.path.append (directories) # to the variable into the built-in module randomimport randomcourses = ['Mathematics', 'Chinese', 'English' Computer] # randomly select a course random_course = random.choice (courses) print (random_course) # Import the built-in math module import math# use radians () to convert the angle to radians rads = math.radians (90) print (rads) # calculate the sin function value print (math.sin (rads)) # Import time module import datetimeimport calendartoday = datetime.date.today () print (today) # check if it is a leap year print (calendar.isleap (2019)) ) # Import operating system module import os# print the directory where the current script is located print (os.getcwd ()) # View the file of the os module # use two underlined print (os.__file__) # Import a browser module import webbrowser# Open the default browser to access a URL: webbrowser.open ("http://placekitten.com/200/300")"

The running effect of the above code:
