How to check if any string from a list of strings is a substring of a string?-CodePudding

Consider the below code:


fruits = ['apple','orange','mango']

description = 'A mango is an edible stone fruit produced by the tropical tree Mangifera indica'.

I need to check if the description string contains any word from the fruits list.

Consider using any along with in:

>>> fruits = ['apple', 'orange', 'mango']
>>> description = 'A mango is an edible stone fruit produced by the tropical tree Mangifera indica'
>>> any(f in description for f in fruits)
True

You could create a list of all the words in the string by splitting it at every " " char. And then check if this list contians the searched words.

fruits = ['apple','orange','mango']
description = 'A mango is an edible stone fruit produced by the tropical tree Mangifera indica'
words = description.split(" ")
for searched in fruits:
   if searched  in words:
      print(f"{searched} found")

You can check this like that:

a=[True if fruit in description else False for fruit in fruits]

And the output will be:

[False, False, True]

A possibility (in case you find the fruit in description syntax confusing) would be to use the __contains__ method, like that:

any(description.__contains__(fruit) for fruit in fruits)
