Answer:
Step-by-step explanation:
I do not have the files listed in the question so I have made two test files with the same names. This code is written in Python, we are assuming that the names on each file are separated by newlines.
f1 = open("GirlNames.txt", 'r') 
f1_names = f1.read() 
f1_names_list = f1_names.split('\\') 
 
f2 = open("BoyNames.txt", 'r') 
f2_names = f2.read() 
f2_names_list = f2_names.split('\\') 
 
print(f1_names_list) 
print(f2_names_list) 
 
boy_or_girl = input("Would you like to enter a boy or girl name or both: ").lower() 
if boy_or_girl == 'boy': 
 name = input("Enter name: ") 
 if name in f2_names_list: 
 print("Yes " + name + " is in the list of most popular boy names.") 
 else: 
 print("No, it is not in the list") 
elif boy_or_girl == 'girl': 
 name = input("Enter name: ") 
 if name in f1_names_list: 
 print("Yes " + name + " is in the list of most popular girl names.") 
 else: 
 print("No, it is not in the list") 
elif boy_or_girl == 'both': 
 girlname = input("Enter Girl name: ") 
 if girlname in f1_names_list: 
 print("Yes " + girlname + " is in the list of most popular girl names.") 
 else: 
 print("No, it is not in the list") 
 boyname = input("Enter name: ") 
 if boyname in f2_names_list: 
 print("Yes " + boyname + " is in the list of most popular girl names.") 
 else: 
 print("No, it is not in the list") 
else: 
 print("Wrong input.")
