How can I check if the characters in a string are in a dictionary of values?

Question

I want to check if the characters in any given string are listed in a dictionary of values (as keys) that i have created, how do I do this?

Answer 1

[char for char in your_string if char in your_dict.keys()]

this will give you a list of all chars in your string that are present as keys in your dictionary.

Eg.

your_dict = {'o':1, 'd':2, 'x':3}
your_string = 'dog'
>>> [char for char in your_string if char in your_dict.keys()]
['d', 'o']
