Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons). Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt. Ex: If the input is:
In Python:
I've received a few errors, what could I be doing wrong?

Ex: If the input is:
file1.txt
and the contents of file1.txt are:
20 Gunsmoke 30 The Simpsons 10 Will & Grace 14 Dallas 20 Law & Order 12 Murder, She Wrote
the file output_keys.txt should contain:
10: Will & Grace 12: Murder, She Wrote 14: Dallas 20: Gunsmoke; Law & Order 30: The Simpsons
and the file output_titles.txt should contain:
Dallas Gunsmoke Law & Order Murder, She Wrote The Simpsons Will & Grace
My Code:
#Define readFile() function
def readFile(file_Name):
dictn = {}
with open(file_Name, 'r') as inp_File:
lines = inp_File.readlines()
for index in range(0, len(lines) - 1, 2):
if lines[index].strip()=='':continue
cnt = int(lines[index].strip())
name = lines[index + 1].strip()
if cnt in dictn.keys():
name_list = dictn.get(cnt)
name_list.append(name)
name_list.sort()
else:
dictn[cnt] = [name]
print(cnt,name)
return dictn
#Define output_keys() function
def output_keys(dictn, file_Name):
with open(file_Name,'w+') as out_File:
for key in sorted(dictn.keys()):
out_File.write('{}: {}\n'.format(key,';'.join(dictn.get(key))))
print('{}: {}'.format(key,';'.join(dictn.get(key))))
#Define output_titles() function
def output_titles(dictn, file_Name):
titles = []
for title in dictn.values():
titles.extend(title)
with open(file_Name,'w+') as out_File:
for title in sorted(titles):
out_File.write('{}\n'.format(title))
print(title)
#Define main() function
def main():
file_Name = input('Enter the file name:')
dictn = readFile(file_Name)
if dictn is None:
print('Error: Invalid file name provided: {}'.format(file_Name))
return
output_file_Name_1 ='output_keys.txt'
output_file_Name_2 ='output_titles.txt'
print("\nKeys:")
output_keys(dictn,output_file_Name_1)
print('\nTitles:')
output_titles(dictn,output_file_Name_2)
main()
