'LIKE' function for Lists

Is there any equivalent 'LIKE' function(like in MySQL) for lists. for example;

This is my list开发者_Python百科:

abc = ['one', 'two', 'three', 'twenty one']

if I give the word "on", it should print the matching words from the list (in this case: 'one', 'twenty one') and if I give "fo", it should print False

You can use list comprehension:

[m for m in abc if 'on' in m]

This roughly translates to "for each element in abc, append element to a list if the element contains the substring 'on'"

>>> abc = ['one', 'two', 'three', 'twenty one']
>>> print [word for word in abc if 'on' in word]
['one', 'twenty one']

Would these list comprehensions suffice?

>>> abc = ['one', 'two', 'three', 'twenty one']
>>> [i for i in abc if 'on' in i]
['one', 'twenty one']
>>> [i for i in abc if 'fo' in i]
[]

You could wrap this in a function:

>>> def like(l, word):
...     words = [i for i in abc if word in i]
...     if words:
...         print '\n'.join(words)
...     else:
...         print False
...
>>> like(abc, 'on')
one
twenty one
>>> like(abc, 'fo')
False
>>>

for x in abc:
    if "on" in x:
        print x

Or, as a function,

def like(str, search):
    res = []
    for x in search:
       if str in x:
           res.append(x)
    return res
