fibonacci range:
you enter a minimum number , and maximum number .
program prints lists numbers between high number of low number

Building counts lines , words and chars – Python

Program counts lines, words and chars
Here are two options

First option

Used: for , if

#!/usr/bin/python
”’
author: Hopeless
task: Write a program that counts lines, words and chars in a given file
”’
file = raw_input(‘please enter file name and locate if need:’)fileo = open(file,’r+’)
chars=0
words=0
lines=0

# calculate number of words
fileo = open(file,’r+’)
for word in fileo.read().split():
if word != ‘ ‘:
if word != ‘\n’:
words+=1
#print word
fileo.close()

# calculate number of chars
fileo = open(file,’r+’)
for word in fileo.read():
if word != ‘ ‘:
if word != ‘\n’:
chars+=1
fileo.close()

# calculate number of lines
fileo = open(file,’r+’)
for word in fileo.read().split(“\n”):
#print word
lines+=1
fileo.close()

print ‘number of words in file :’, words
print ‘number of chars in file :’, chars
print ‘number of lines in file :’, lines

 

First we have to download a file that you can work on it.
Then we run the Python file
And put the name of the file for inspection when requested to do so

second option

Used: import sys , if , try , except , else

if len(sys.argv) > 1:

filex.close()

#print # of lines
print ‘Lines:’, text.count(‘\n’)+1

#print #of words
wordcount = text.split(None)
print ‘Words:’, len(wordcount)

#print # of chars
print ‘Chars:’, len(text)

except Exception, e:
print ‘I can\’t find the file, maybe try full path?…’
exit(0)

else:
print ‘Hi this prog it like linux wc…’
print ‘Usage: checkfilesgil.py [filename]\n’
print ‘Example: checkfilesgil.py sheker.txt’

 

First we have to download a file that you can work on it.
Then we run the Python file And that line we will put the filename
