Searching for a string value in a list

Question

My list is a=['Name','Age','Subject'] and I want to search whether an input by the user exists in this list or not.

Let's say the user enters x='name', how do I search for x in this list a (case-insensitively)?

Answer 1

I think the following code might help you. You have to string modification methods lower()/upper(). I used lower here, it changes any case of each character to lower case. e.g. after using 'NaMe'.lower() to NaMechanged to `'name''. I changed both the input string and list elements and checked whether the input is in the list. That's all.

Code

a=['Name','Age','Subject'] 
a = [a.lower() for a in a]
user_input = input("Put the input: ").lower()
if user_input in a:
    print("Match")
    
else:
    print("Mismatch")

Output

> Put the input: AGE
> Match

Answer 2

If you want to do a case sensitive search in the list you can do,

x = "name" # input from the user
l = ['Name','Age','Subject']

if x in l:
    print("Found a match")
else:
    print("No match")

If you want to do a case insensitive search in the list you can do,

x = "name" # input from the user
l = ['Name','Age','Subject']

if x.lower() in list(map(lambda x: x.lower(), l)):
    print("Found a match")
else:
    print("No match")

Answer 3

Maybe this is what you need:

a = ['Name','Age','Subject']
x = input('').title()
b = x in a
print(b)

Answer 4

You can do as follows Without casting the whole list:

b = input("please enter a string:")
ismatch =b.title() in a
print(ismatch)

>>> please enter a string:
>Age
>>> True

Answer 5

a=['Name','Age','Subject']
if 'Name' in a:
    print "yes"
