Question

Define a function named how_many_substr_of_string(...) which receives two parameters, the first parameters is a list with strings (name it  listst) and the second parameter is a single string (name it st). The function should return a number, indicating how many of the strings in the list listst are substrings in the string st

As an example, the following code fragment:

listst = ["a","bc","dd"] st = "abc"

res = how_many_substr_of_string(listst,st) print (res)

should produce the output:

Language Python

Answer 1

def how_many_substr_of_string(listst,st):
  
# using list comprehension  
# to get string with substring  

return len([i for i in listst if i in st])

listst = ['ab', 'abc', 'efg', 'bc']

st = 'abcde'

result=how_many_substr_of_string(listst, st)
print(result)

Output:
