#File_processing 7.1 Write a program that prompts for a file name, then opens that file and reads through the file, and print the contents of the file in upper case. Use the file words.txt to produce the output below. You can download the sample data at http://www.py4e.com/code3/words.txt

7.1.py

fname = input("Enter file name: ")
try :
    fh = open(fname)
except:
    print('Cannot open the file ',fname ,'please try again')
    quit()

for line in fh :
    line = line.upper()
    line = line.rstrip()
    print(line)

Use words.txt as the file name

fname = input("Enter file name: ")
fh = open(fname)
#fh.upper()
for x in fh:
y=x.rstrip()
print(y.upper())

The best Answer

fname = input("Enter file name: ")
try :
fh = open(fname)
except:
print('Cannot open the file ',fname ,'please try again')
quit()
txt = fh.read().strip().upper()
print(txt)
