Example-4: Importing all functions from another Python file In this scenario, Let us take the compute.py file but with one more function added to compute compound interest. Here, we will import all the functions present in compute.py file. The compute.py contains two functions to compute sim...
echo "This is another file" > file2.txt 现在,通过键入以下命令将第一个文件重命名为file1.txtmv file.txt file1.txt 如果您现在列出当前目录的内容,您会看到file1.txt和file2.txt。你可以cat每个文件,以确保它们是你创建的。接下来,让我们将file1.txt复制到文件夹结构中的上一级目录。类型cp file1.txt...

if__name__=='__main__':print('This program is being run by itself')else:print('I am being imported from another module') 运行结果 每个Python模块都有它的__name__,如果它是'__main__',这说明这个模块被用户单独运行,我们可以进行相应的恰当操作。
Learn how to open, read, write, and perform file operations in Python with built-in functions and libraries. A list of modes for a file handling.
Now, you’ll create a module where you store your decorators and that you can use in many other functions.Create a file called decorators.py with the following content:Python decorators.py def do_twice(func): def wrapper_do_twice(): func() func() return wrapper_do_twice ...
All functions in the subprocess module are convenience wrappers around the Popen() constructor and its instance methods. Near the end of this tutorial, you’ll dive into the Popen class. Note: If you’re trying to decide whether you need subprocess or not, check out the section on deciding...
Method 2: Using seek() and truncate() Functions The “seek()” is used to set the pointer at the start of the program. The “truncate()” function removes the file’s data. In the example given below, the “seek()” and “truncate()” functions are used to overwrite the selected ...
And when it comes to reusing code in Python, it all starts and ends with the humblefunction. Take some lines of code, give them a name, and you’ve got a function (which can be reused). Take a collection of functions and package them as a file, and you’ve got amodule(which can...
