Find strings in list using wildcard

Question

I am looking for some file names in a list using a wildcard.

from datetime import date
dt = str("RT" + date.today().strftime('%d%m'))
print dt # RT0701

Basically I need to find this pattern dt + "*.txt" :

RT0701*.txt

In this list:

l = ['RT07010534.txt', 'RT07010533.txt', 'RT02010534.txt']

How can i do that with a for loop?

Answer 1

You can use fnmatch.filter() for this:

import fnmatch
l = ['RT07010534.txt', 'RT07010533.txt', 'RT02010534.txt']
pattern = 'RT0701*.txt'
matching = fnmatch.filter(l, pattern)
print(matching)

Outputs:

['RT07010534.txt', 'RT07010533.txt']
