How to check a list for matches of in input-CodePudding

I am trying to make a program that can check an input, then it will be able to search through a list for matches in that string (no spaces) List: {'123', '1234', '12345', '123456', password} input: Hello231234

I want it so that it can check my input for any matches in the list. (I am a beginner in python)

First, a list is noted with brackets: []. Whats is noted as {}, can be either a dictionary if it has key:value as {'name: 'Mike', 'age': 78} either a set as {1, 3, 4, 6, 8}. A set is similar to a list but orders your values and doesn't keep duplicates.

set(["A", 2, True, 3, 3, "a", True, 3.4, "z", "A", True, "z"])

>>> {2, 3, 3.4, 'A', True, 'a', 'z'}

Look for the different data structures in python to understand more of what you can do with it!

For your problem, you want to use a list.

input = "Hello231234"
liste = ['123', '1234', '12345', '123456', 'password']

input in liste

>>> False

By doing that, you check if your input is in liste. By saying input in liste it will return a boolean, True if in, or False if not.

I'm interpreting this as you are looking to see if any of the strings in your list occur in the input (basically the reverse of what @Marc assumed).

In that case, you can loop through your list, and check if any of them exist in the input:

input = "Hello231234"
wordList = ['123', '1234', '12345', '123456', 'password']
match = False
for word in wordList:
    if word in input:
        match = True
        
print(match)
