is it possible for me to check if I input a name and if its in the list of names in a txt file?-CodePudding

I tried to use the last part of the code but it doesn't work it just says false there might be some errors and if your wondering i have a txt file with names

import string
string.ascii_letters 
'abcdefghijklmnOpqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
import random
letter = random.choice(string.ascii_letters)
print(letter)
file = open("names.txt")

found = [] #Result will Store
for m in file:
    if m.startswith(letter): #It will check if the input value match with from begining of the signl world
        found.append(m) # Store the value if match
for f in found:
    print("\n" f)
print("Total Words is " str((len(found))))

rika = input("name: ")

print(rika in found)

CodePudding user response：

I did an example, where names.txt contains:

Thomas
Peter
Jens

Your Code:

import string, random
letter = random.choice(string.ascii_letters)
print(letter)
with open("names.txt") as file:
    found = [] #Result will Store
    for m in file:
        if m.startswith(letter): #It will check if the input value match with from begining of the signl world
            found.append(m.strip()) # Store the value if match, remember to strip newline
    for f in found:
        print("\n" f)
    print("Total Words are " str(len(found)))
    if found:
        rika = input("name: ")
        print(rika if rika in found else "Not found")

Result:

J

Total Words is 1
name: Jens
Jens

I changed your file handling and open it using a context manager, in that way it will automatically close the file after using it. I also checked if found contain any data before asking for input.
