global someVar someVar = 55 This would change the value of the global variable to 55. Otherwise it would just assign 55 to a local variable. The order of function definition listings doesn't matter (assuming they don't refer to each other in some way), the order they are called does....
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...
Inside load_earth_image(), you access the three global constants directly, just like you would do with any global variable in Python. However, you don’t change the value of any of the constants inside the function. Now you can reuse these constants in other related functions as well. Usi...
Note python has this really weird error if you define local variable in a function same name as the global variable, program will promptUnboundLocalError. child class object overrides parent class methods input: classfruit:defprint(self):print('a')defeat(self):print('b')classapple(fruit):defpr...

虽然可以在函数中对全局变量进行赋值操作,但是那些变量必须用global关键字声明成全局的才行。 a = None def bind_a_variable(): global a a = [] bind_a_variable() print(a) #[] 注意:我常常建议人们不要频繁使用global关键字。因为全局变量一般是用于存放系统的某些状态的。如果你发现自己用了很多,那可能...
