Can I change my variable name in Python? For example, I have a string x, and I want to change string x variable name to y, how can I do it?

CodePudding user response：

Python variables are references to objects, so you can simply create a second name pointing to the existing object and delete the old name:

y = x
del x

Ideally, the good approach will be renaming the variable, like y = x

But you can do this in weird approach with using globals()

In [1]: x = 10

In [2]: globals()['y'] = globals().pop('x')

In [3]: 'x' in globals()
Out[4]: False

In [4]: 'y' in globals()
Out[4]: True
