Write a program that first reads in the name of an input file and then reads the input file using the file
Subject:Computer SciencePrice:5.87 Bought8
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:
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
THIS IS WHAT I HAVE
file = input()
with open(file) as f:
data = f.readlines()
dict_info = {}
for i in range(0,len(data)-1, 2):
season = data[i].strip()
name = data[i+1].strip()
if(season in dict_info):
dict_info[season].append(name)
else:
dict_info[season] = [name]
keys = list(dict_info.keys())
keys.sort()
with open('output_keys.txt', 'w') as f:
for key in keys:
names = '; '.join(name for name in dict_info[key])
f.write(str(key)+': '+names+"n")
names = []
for item in dict_info:
for name in dict_info[item]:
names.append(name)
names.sort()
with open('output_titles.txt', 'w') as f:
for name in names:
f.write(name+'n')
Input
file2.txt
Your output
07: Rules of Engagement; Medium; Lux Video Theatre
08: Mama; Barney Miller; Castle
10: Will & Grace; Smallville; Modern Family; Friends
11: Cheers; The Jeffersons
12: Murder, She Wrote; NYPD Blue
14: Dallas; Bonanza
15: ER
20: Gunsmoke; Law & Order; Law & Order: Special Victims Unit
30: The Simpsons
Expected output
7: Rules of Engagement; Medium; Lux Video Theatre
8: Mama; Barney Miller; Castle
10: Will & Grace; Smallville; Modern Family; Friends
11: Cheers; The Jeffersons
12: Murder, She Wrote; NYPD Blue
14: Dallas; Bonanza
15: ER
20: Gunsmoke; Law & Order; Law & Order: Special Victims Unit
30: The Simpsons

Answer:
def main():
file = input('Enter input file name: ') #get file nae
dict_info = {} #data dictionary
with open(file, 'r') as infile:
lines = infile.readlines() #get file data
for i in range(0, len(lines) - 1, 2):
if lines[i].strip()=='':continue #strip down the empty space
count = int(lines[i].strip())
name = lines[i + 1].strip()
if count in dict_info.keys():
names = dict_info.get(count) #get data
names.append(name)
names.sort() #sort them
else:
dict_info[count] = [name]
print(count,name)
if dict_info is None:
print('Error: Invalid file name provided: {}'.format(file))
return
outFile1 ='output_keys.txt'
outFile2 ='output_titles.txt'
#print data into files
with open(outFile1,'w+') as output:
for i in sorted(dict_info.keys()):
output.write('{}: {}\n'.format(i,';'.join(dict_info.get(i))))
print('{}: {}\n'.format(i,';'.join(dict_info.get(i))))
titleNames = []
for i in dict_info.values():
titleNames.extend(i)
with open(outFile2,'w+') as output:
for i in sorted(titleNames):
output.write('{}\n'.format(i))
print(i)
main()
