现在我们希望在另一个Python文件main.py中访问another_file.py中定义的变量my_variable: AI检测代码解析 # main.py# 方法一:使用import语句importanother_fileprint(another_file.my_variable)# 方法二:使用from ... import ...语句fromanother_fileimportmy_variableprint(my_variable)# 方法三:使用exec()函数file...

sys.path is initialized from these locations:The directory containing the input script (or the current directory when no file is specified). PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH). The installation-dependent default. import 执行时,会尝试使用以下...
input返回的类型是string类型,所以可根据需要进行类型转换,如variable=int(input()) 元组、列表、字典 11.1 元组 列表 元组tuple:以小括号或者无括号表示,是一连串有顺序的数字,list以中括号命名。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 a_tuple=(12,3,5,15,6)another_tuple=12,3,5,15,6a_lis...
import urllib 以使其可供使用。urllib库使用以下语法:image = urllib.URLopener() image.retrieve ("http://www.website.com/imageFile.jpg", "imageFile.jpg") 其中发送给URLopener.retrieve()函数的第一个参数是文件的 URL,第二个参数是文件将要保存的本地文件名。第二,文件名参数遵循 Linux 文件和目录...
To see this clearly, you can assign the result of run() to a variable, and then access its attributes such as .returncode:Python >>> import subprocess >>> completed_process = subprocess.run(["python", "timer.py"]) usage: timer.py [-h] time timer.py: error: the following ...

The somewhat cryptic output means that the first variable refers to the local first_child() function inside of parent(), while second points to second_child().You can now use first and second as if they’re regular functions, even though you can’t directly access the functions they point...
单下划线常用来实现模块级私有化,当我们使用“from mymodule import *”来加载模块的时候,不会加载以单下划线开头的模块属性。也就是前导下划线的确会影响从模块中导入名称的方式。 假设你在一个名为my_module的模块中有以下代码: # This is my_module.py: ...
This is useful if the name of a module conflicts with a variable you have declared in your code. It is also useful if you want to reference another module that shares the same name. Suppose we want to import the time module into your code. We are going to import the time module and...
