How to compare a substring with a list of elements in Python?

I am trying to compare substring from a string that I am getting from reading a .txt file and matching it with an element of the list.

String from the .txt file is as follows:

 1. Blood 75.6 gm% 12-14    
 2. Rash 15.4 tm/m 54-89

I have a list called data which includes the words that are occuring as a first word in the string. So,

data = ['blood', 'Rash']

f = open('my.txt', r)
for x in f:
    if x.find(str(data)):
    # Do something

How do I match these both and then do my operations on it?

You can use the any operator which will return true if any word in the line of f matches any string in data.

f = open('my.txt', r)
for x in f:
    if any(y in x for y in data):
        #Do operation

or if you want to check that every line contains at least one string in data. You can use the all operator which will return true if all lines contain a string in data:

f = open('my.txt', r)

if all(any(y in x for y in data) for x in f):
   #Do operation

with open("my.txt") as f:
    for line in f:
       for i in data:
           if i in line:
               do_operation()

Is this what you were asking for?
