How to get a substring from a string if one string is found

Question

This is a string: \texample\tDart_181120172410.jpg\tImgCaption\t

Is there anyway to get the Dart_181120172410.jpg and could say to get this substring if only it contains .jpg at the end. The actual string is even longer

it it tab-delimited (\t), Split by tabs, check each for ending with .jpg, done - see answer — Patrick Artner

You can use split()

>>> image_name = s.split('\t')[2]
>>> if '.jpg' in image_name:
        print(image_name)
Dart_181120172410.jpg

Like this:

s = "a.jpg\tnot.llm\tp.jpg\tc.jpg\te.gif\tnix.txt"

all_jpegs = [x for x in s.split('\t') if '.jpg' in x]

print(all_jpegs)

Output: ['a.jpg', 'p.jpg', 'c.jpg']

guillaume-dedrie made a good point in the comment - this will lead to false positives for s=some.file\tthisisno.jgp.gif\tsomemore.files. Changing it to

s = "a.jpg\tnot.llm\tp.jpg\tc.jpg\te.gif\tnix.txt\tnot.jpg.gif\tthis.JPG"
better_jpegs = [x for x in s.split('\t') if x.lower().endswith('.jpg')]

print(better_jpegs)

would eleminate that and also handle '.JpG' or '.JPG'

You can use regex in python for this.
