I need to detect if a string matches a substring contained in a list, and get the index of the matching substring to assign a value to a variable. Here's the code :
filename = "rec_1.2_LUNCHPLAY_20220616_1645.mp4"
year = '2022'
studio = ['arena', '-1.2', '1.2', '1.3', '1.4', '1.5', '1.8', '1.9', '2bis']
month = [f'{year}01', f'{year}02', f'{year}03', f'{year}04', f'{year}05', f'{year}06']
I'm expecting the output to be [2]
and [5]
.
Any chance someone could help me on that ?
CodePudding user response:
Use enumerate()
to iterate over the items in a list and keep track of the current item's position.
for position, substring in enumerate(substrings):
if substring in message:
print(position)
break
But even if you didn't know about enumerate
, there is another straightforward solution using range()
:
for position in range(len(substrings)):
if substrings[position] in message:
print(position)
break

year = '2022'
studio = ['arena', '_1.2', '1.2', '1.3', '1.4', '1.5', '1.8', '1.9', '2bis']
month = [f'{year}01', f'{year}02', f'{year}03', f'{year}04', f'{year}05', f'{year}06']
studio_index = None
month_index = None
for idx, st_match in enumerate(studio):
if st_match in filename:
studio_index = idx
break
for idx, mo_match in enumerate(month):
if mo_match in filename:
month_index = idx
break
print(f'studio index: {studio_index}')
print(f'month index: {month_index}')
Result:
studio index: 2
month index: 5
