How to see variables names in Python?

Question

I am a newbie python user, I just migrated from R. Is there a function in Python like View() or ls() in R that lets you see the variables stored in the memory

But its giving me everything that I dont even need , isnt there a way to print just the names? — Spandyie

dir() returns a list of names in the current scope. Since everything is an object in Python, there isn't a difference (to dir) between an imported module and a variable holding a string. — MattDMo

You can use locals() to see all the variables in the local scope or globals() to see everything in the global scope. To get exactly what you want:

>>> import re
>>> x = 5
>>> y = 7
>>> foo = object
>>> [x for x in locals().keys() if not x.startswith('__')]
['re', 'x', 'y', 'foo']

If you also need the values:

>>> {key: val for key, val in locals().items() if not key.startswith('__')}
{'y': 7, 're': <module 're' from '/Users/ian/venv/lib/python2.7/re.pyc'>, 'foo': <object object at 0x103b1d0e0>, 'x': 5}
