Python：在函数之间传递变量

Python：在函数之间传递变量

这是实际发生的情况：

global_list = []def defineAList():    local_list = ['1','2','3']    print "For checking purposes: in defineAList, list is", local_list     return local_listdef useTheList(passed_list):    print "For checking purposes: in useTheList, list is", passed_listdef main():    # returned list is ignored    returned_list = defineAList()    # passed_list inside useTheList is set to global_list    useTheList(global_list)main()

这就是你想要的：

def defineAList():    local_list = ['1','2','3']    print "For checking purposes: in defineAList, list is", local_list     return local_listdef useTheList(passed_list):    print "For checking purposes: in useTheList, list is", passed_listdef main():    # returned list is ignored    returned_list = defineAList()    # passed_list inside useTheList is set to what is returned from defineAList    useTheList(returned_list)main()

您甚至可以跳过临时

returned_list

变量，并将返回值直接传递给

useTheList

：

def main():    # passed_list inside useTheList is set to what is returned from defineAList    useTheList(defineAList())
