Hello,
If we want to check if a string contains any/all of several other
strings we have to use several or/and conditions or any/all.
For any:
|if ('string1' in master_string or 'string2' in master_string
or 'string3' in master_string):
or
ifany(item inmaster_string foritem in['string1','string2','string3']):
Trivial with re module, which will answer the question in one pass.
For all:

||if ('string1' in master_string and 'string2' in master_string
and'string3' in master_string):
or
||ifall(item inmaster_string foritem in['string1','string2','string3']):
Tougher.
Are the strings guaranteed to not be prefixes of each other?
Do you want to allow overlaps?
Can do in one pass by compiling a new re every time an item is found.
If overlaps not wanted, re.iterfind will find all occurrence of any, so
feed to set and see if all found.
