#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)

fname = input("Enter file name: ")
fh = open(fname)
fr= fh.read()
fs=fr.rstrip()
print(fs.upper()

Use words.txt as the file name

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

Use words.txt as the file name

fname = input("Enter file name: ")
fh = open(fname)
dh=fh.read( )
lx=dh.upper( ).rstrip( )
print (lx)

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

Write a program that prompts for a file name, then opens that file and reads through the file, looking for lines of the form:
X-DSPAM-Confidence: 0.8475
Count these lines and extract the floating point values from each of the lines and compute the average of those values and produce an output as shown below. Do not use the sum() function or a variable named sum in your solution.

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)
