列出用户定义的变量，python [英] List user defined variables, python

问题描述

我正在尝试遍历 Python 脚本中设置的变量.我遇到了以下情况:

I am trying to iterate through the variables set in a python script. I came across the following:

枚举或列出[此处为您最喜欢的语言]

在第一个例子中:

#!/us/bin/python                                                                                    

foo1 = "Hello world"
foo2 = "bar"
foo3 = {"1":"a", "2":"b"}
foo4 = "1+1"

for name in dir():
    myvalue = eval(name)
    print name, "is", type(name), "and is equal to ", myvalue

它列出了存储在内存中的所有变量.我想隔离我在脚本中创建的变量，而不是列出默认创建的系统变量.有没有办法做到这一点?

It lists all the variables stored in memory. I want to isolate the variables I have created in my script and not list the system variables created by default. Is there any way to do this?

推荐答案

如果您不将任何下划线放在变量前，您可以这样做:

If you don't put any underscores in front of your variables you could do:

#!/us/bin/python                                                                                    

foo1 = "Hello world"
foo2 = "bar"
foo3 = {"1":"a", "2":"b"}
foo4 = "1+1"

for name in dir():
    if not name.startswith('__'):
        myvalue = eval(name)
        print name, "is", type(myvalue), "and is equal to ", myvalue
