Answer 1

Implemented the code as per the requirement. As python is tab specific, you may not get the formatted text while copying the code,
so I'm attaching the screenshots of the code for reference. Please make sure when you are executing the below code you have same format, especially tabs.

Please comment if any modification required.

Code:

====

import sys
def file_commands(file_name):
sum=0
count=0
with open(file_name) as file:
for line in file:
if(line.split()[0]=='u'):
for word in line.split()[1:]:
print(word.upper()+" ", end='')
print()
else:
for str_num in line.split()[1:]:
num = int(str_num)
sum = sum+num
count = count+1
print(int(sum/count))
sum=0
count=0

if __name__ == "__main__":
file_commands(sys.argv[1])

code screenshot:

==============

1 import sys 2 def file_commands (file_name): 3 sum=0 4 count=0 5 with open(file_name) as file: 6 for line in file: 7 if(line.split()[0]=='u'): 8 for word in line.split()[1:]: 9 print(word.upper()+" ", end='') 10 print() 11 else: 12 for str_num in line.split()[1:]: 13 num = int(str_num) 14 sum = sum+num 15 count = count+1 16 print(int (sum/count)) 17 sum=0 18 count=0 19 20 if _main__": 21 file_commands (sys.argv[1]) name

output:

=====

HELLO WORLD! 4.
