So basically I have a huge list of strings, for example
list = ["hello", "my", "name", "is"]
etc...
and I want to ask the user a question, if the user responses with a word that is in my list I want to replace it with "yes". How would I do this, everything that I have tried has failed. Thanks!
List comprehension:
# user input in user_input
new_list = [item if item != user_input else "yes" for item in old_list]
This replaces anything that's equal to the user_input with "yes".
Tip: don't shadow the built-in list.
Output:
>>> old_list = ["hello", "my", "name", "is"]
>>> user_input = "hello"
>>> new_list = [item if item != user_input else "yes" for item in old_list]
>>> new_list
['yes', 'my', 'name', 'is']
Imagine this is your list
INPUT_MATCH = 'yes'
L = ["hello", "my", "name", "is"]
You are asking user to input
user_input = raw_input("Enter your input")
if user_input in set(L): #reason to convert list to set for less expensive search
L[L.index(user_input)] = INPUT_MATCH
