To be more precise: i=1 def f(n): while i<n: x_i = i**2 ##this writing is wrong I would like here to have x_1 or x_2 ... (depending on i) return (x_1,x_2,x_3 .....)Others have already suggested a list, which IMHO is the best option. However if for some reason the zero based index of a list is an issue for you then you could use your naming scheme in a dictionary: def f(n): values = {} root = 'x_' for n in range(1,n+1): values[root+str(n)] = n**2 return values You can then access the values with, for example: print (values['x_2']) But unless you are reading the variable names from a file/network or a user then the numerical index of a list will usually be easier to work with.
If zero based indexing is an issue I'd just write:- values = [None] to start with. -- My fellow Pythonistas, ask not what our language can do for you, ask what you can do for our language.
