Can someone help me with my code?

Question

Write a program that reads the contents of the two files into two separate lists. The program displays a menu of two options: first option allows the user to enter a letter and the program should prints lists of girls and boys names that begin with that letter. Second option: allows the user to enter a length of a name and the program should prints lists of girls and boys names that have the same length.

girlNamesfile = open("GirlNames.txt", "r")
girlNamesList = []

girlNames = girlNamesfile.readline()

while girlNames != "":
girlNamesList.append(girlNames)
girlNames = girlNamesfile.readline()

print(girlNamesList)

boyNamesfile = open("BoyNames.txt", "r")
boyNamesList = []

boyNames = boyNamesfile.readline()

while boyNames != "":
boyNamesList.append(boyNames)
boyNames = boyNamesfile.readline()

print(boyNamesList)

Answer 1

I dont have a complete answer, but, instead of using the readline() and appending the line in a list, file objects have a method called readlines() which returns a list of all the lines in the file.

I'll edit this with more info after work

Answer 2

1) Ok so, for your option, you can obtain the names with:

names_iter = filter(lambda name: name[0] == letter, girlNamesList + boyNamesList)

filter returns a filter object, which is an iterable. You can convert it to list(or tuple), or print them out like:

print(*names_iter, sep='\n')

2) Using the same approach as option 1

names_iter = filter(lambda name: len(name) == length, girlNamesList + boyNamesList)

If you want to read more on filter, (and also map):

@LDSD thank you so much

Answer 4

updated:

girlNamesfile = open("GirlNames.txt", "r")
girlNamesList = []

girlNames = girlNamesfile.readline()

while girlNames != "":
girlNamesList.append(girlNames)
girlNames = girlNamesfile.readline()

print(girlNamesList)

boyNamesfile = open("BoyNames.txt", "r")
boyNamesList = []

boyNames = boyNamesfile.readline()

while boyNames != "":
boyNamesList.append(boyNames)
boyNames = boyNamesfile.readline()

print(boyNamesList)
int(input("Enter 1 for list of names begin with a letter"\n"Enter 2 for list of names that have the same length"))

if option ==1:
letter= input("Enter a letter" print(letter))
print("list of boy names begin with" letter)
print(letter.find)
else
:
length =int(input("Enter a length"))
print(length)
