How can I check if any of the strings in an array exists in another string?
Like:
a = ['a', 'b', 'c'] str = "a123" if a in str: print "some of the strings found in str" else: print "no strings found in str" That code doesn't work, it's just to show what I want to achieve.

You can use any : a_string = "A string is more than its parts!" matches = ["more", "wholesome", "milk"] if any(x in a_string for x in matches): Similarly to check if all the strings from the list are found, use all instead of any .
Using regular expressions, we can easily check multiple substrings in a single-line statement. We use the findall() method of the re module to get all the matches as a list of strings and pass it to any() method to get the result in True or False.
Using find() to check if a string contains another substring We can also use string find() function to check if string contains a substring or not. This function returns the first index position where substring is found, else returns -1.
Using Python's "in" operator The simplest and fastest way to check whether a string contains a substring or not in Python is the "in" operator . This operator returns true if the string contains the characters, otherwise, it returns false .
You can use any:
a_string = "A string is more than its parts!" matches = ["more", "wholesome", "milk"] if any(x in a_string for x in matches): Similarly to check if all the strings from the list are found, use all instead of any.
