This might not be the most efficient way, but:
>>> set("abc") <= set("adfbdfc")
True
>>> set("abce") <= set("adfbdfc")
False
If you want to check for substrings longer than one character, this
won't work. A solution then is to define a custom function:
def all_in(string, substrings):
for substring in substrings:
if substring not in string:
return False
return True
