Note: If you create a new localvariableinside a function with the same name as a global variable, it will not override the value of a global variable. Instead, the new variable will be local and can only be used inside the function. The global variable with the same name will remain un...
# File3.py# 导入全局变量fromFile1importglobal_variable# 打印全局变量print(global_variable)# 输出: 20 1. 2. 3. 4. 5. 6. 7. 通过使用global关键字,在不同的文件中可以共享全局变量的值。在上面的示例中,在File2.py中修改了全局变量的值后,在File3.py中也能看到更新后的值。 方法三:使用config模...
另一种方法是使用global关键字,在一个文件中定义全局变量,然后在另一个文件中使用global关键字声明这个变量。以下是一个示例: 在file1.py中定义全局变量: # file1.pyglobal_variable="I am a global variable" 1. 2. 在file2.py中引用file1.py中的全局变量: # file2.pyfromfile1importglobal_variableprint...
解释下,当我们在test/test1.py中写了from test2 import *这句代码,程序不是直接导入test2下的所有模块,而是导入__init__.py文件并自动运行,由于我们写了__all__ = ['file_a', 'file_b', 'file_c', 'test_d'],file_a和file_b是当下包中的模块,file_c是我们从test3包中导入的,test_d是__init_...

A global variable in Python is a variable defined at the module level, accessible throughout the program. Accessing and modifying global variables inside Python functions can be achieved using the global keyword or the globals() function. Python handles name conflicts by searching scopes from local...
# Filename : helloworld.py print'Hello World' (源文件:code/helloworld.py) 为了运行这个程序,请打开shell(Linux终端或者DOS提示符),然后键入命令python helloworld.py。如果你使用IDLE,请使用菜单Edit->Run Script或者使用键盘快捷方式Ctrl-F5。 输出如下所示。
