如何找出熊猫数据框的功能？

Question

My question is theoretical. Let's suppose I have a pandas Data Frame in python and I want to check what are the operations which can be performed on it. For eg we can perform rename, sum, mean etc. on a pandas data frame. But is there any command which will give me the complete list of these kind of operations?

Answer 1

You can always use dir command and check all available functions :)

Example:

Answer 2

You can use the command dir to inspect your dataframe -

df = pd.DataFrame([[1, 2, 'a']], columns =['A', 'B', 'C'])
for d in dir(df)[:10]: print (d)

Output (first 10 lines) -

A
B
C
T
_AXIS_ALIASES
_AXIS_IALIASES
_AXIS_LEN
_AXIS_NAMES
_AXIS_NUMBERS
_AXIS_ORDERS

Answer 3

Well I think there isn't a command to list all available commands, but you can install a basic Python Extension to help you out.

If you are using VS Code or Atom just go to Extension Marketplace, there are bunch of them from you can choose.
