Create a list of strings with consecutive numbers appended

I'm sure there must e an easy way to do this: I want to create a list which will eventually become column names for a DataFrame. There will be 13 columns, each representing a period in time, called "Period n", where n is the period number. I think there's probably a way to build this list via loop, but I will show what I tried to do:

col_no = list(range(1,14)) col_name = ['Period' for n in range (1,14)] col_list = col_name + col_no  print(col_list)  ['Period',  'Period',  'Period',  'Period',  'Period',  'Period',  'Period',  'Period',  'Period',  'Period',  'Period',  'Period',  'Period',  1,  2,  3,  4,  5,  6,  7,  8,  9,  10,  11,  12,  13] 

Then I tried:

col_list = list(zip(col_name + col_no)) print(col_list)  [('Period',),  ('Period',),  ('Period',),  ('Period',),  ('Period',),  ('Period',),  ('Period',),  ('Period',),  ('Period',),  ('Period',),  ('Period',),  ('Period',),  ('Period',),  (1,),  (2,),  (3,),  (4,),  (5,),  (6,),  (7,),  (8,),  (9,),  (10,),  (11,),  (12,),  (13,)] 

Basically, I just wanted an easily generated list that reads "Period 1", "Period 2", etc. I'm pretty new to Python, and pretty stumped.Thanks in advance

 


You can concatenate them (the number and the word Period) together while the loop iterates.

Python 3.6

print([f'Period {i}' for i in range(1, 14)]) 

Other versions of Python

print(['Period {}'.format(i) for i in range(1, 14)])
