Im trying to validate the user's input so he/she only types in 'all' or 'sel' (not case sensitive). Might just be some syntax mistake im making.
choice=input('Type "all" or "sel": ')
choice=choice.lower()
while choice!=('sel' or 'all'):
choice=input('Invalid input. Try again: ')
choice=choice.lower()
This only works if I type in 'sel', but not 'all'.

I am modifying some Python code that is used in an ODOO Addon.
How does the logic for the following statement work?
origin = (move.group_id and move.group_id.name or (move.origin or move.picking_id.name or "/"))
Values
move.group_id is an object
move.group_id.name is a string value
move.origin is a string value
move.picking_id.name is a string
the result is "origin" is assigned the string value of "move.group_id.name"
What is this kind of assignment called?
(I tried to google this first but its not inline if logic and I have a lack of words for what this is called.)

How would I accept multiple options/answers for an input. For example:
if player_ship == 'Transport' or 'TRANSPORT' or 'transport':
print('You successfully purchased a Transport Ship!\n\n')
The below will ensure that case sensitivity is not a problem.
if player_ship.lower() == 'transport'
If you genuinely need to check against specific values, this will work:
if player_ship in {'Transport', 'TRANSPORT', 'transport'}

I have been trying to change the words in one of the columns of my data frame such that it will replace all the words except some keywords which I want to leave as it is.
I tried doing this:
df['col]=df['col].where(lambda x: x == ('A'or'B'or'C'),'others')
My plan is to replace every word that isn't A or B or C with others.
The code worked for A but B and C were replaced.
How do I go about this please?
NB: I am trying to improve my python skill and have searched the entire stack-overflow before asking this question.
Thank you for your help.
