converting??? [Inline code to function with loop]

[bratiskovci]

1. How do I change the program so that the program does not terminate after completing one conversion. Instead, the program should continue to convert values until the user indicates that he/she wishes to quit.
2. How do you change the structure of the program so that ALL conversion computations are in a function of their own.
Input: the user inputs the amount in one of the following forms:
# C value
# F value
# CM value
# I value
#
# C - is a celcius value. Program converts to fahrenheit
# F - is a fahrenheit value. Program converts to celcius
# CM - is a centimetre value. Program converts to inches
# I - is an inch value. Program converts to centimetres

import sys

# Prompt user
sys.stdout.writ e( "Enter a value to convert: ")

# Read in a line from the keyboard
lineElements = sys.stdin.readl ine().split(" ")

# If the value is Celcius, convert to Fahrenheit
if lineElements[0].lower() == 'c':
print "%s degress celcius is %.2f degrees fahrenheit." \
% ( lineElements[1].strip(), (float(lineElem ents[1])*9.0/5.0)+32)

# If the value is Fahrenheit, convert to Celcius
elif lineElements[0].lower() == 'f':
print "%s degress fahrenheit is %.2f degrees celcius." \
% ( lineElements[1].strip(), (float(lineElem ents[1]) - 32) * 5.0/9.0)

# if the value is in centimetres, convert to inches
elif lineElements[0].lower() == 'cm':
print "%s centimetres is %.2f inches." % ( lineElements[1].strip(),
(float(lineElem ents[1]) * 0.3937))

# if the value is in inches, convert to centimetres
elif lineElements[0].lower() == 'i':
print "%s inches is %.2f centimetres." % ( lineElements[1].strip(),
(float(lineElem ents[1]) * 2.54))

Please post back using [ code ] [ /code ] (but without spaces) tags around your code. Otherwise, we can't see the structure of you code. Thanks.

for example

 
# this is code

To answer the first question, do the following:

import sys
 
input = ""
 
while(input != "quit\n"):
 input = sys.stdin.readline()
 print "you typed : " + input
 

You see what happens here? We do repeat (through the while loop) until input is equal to "quit\n". I think you are able to figure out question 2 for yourself.

Your post is still not quite right. Please read the sticky at the top of this forum or posting guidelines in that panel to the right or the gray lettering in the background when you are typing in your post. You can edit you post until it look like this:

### Prompt user
##sys.stdout.write( "Enter a value to convert: ")
##
### Read in a line from the keyboard
##lineElements = sys.stdin.readline().split(" ")
# define the function
def convert(selector, valStr, value):
    # if the value is in centimetres, convert to inches
    elif selector == 'cm': # test for this first
        print "%s centimetres is %.2f inches." % (valStr,
        value * 0.3937)
    # If the value is Celcius, convert to Fahrenheit
    if selector.startswith('c'): # could be 'ce'
        print "%s degress celcius is %.2f degrees fahrenheit." \
        % (valStr, (value * 9.0/5.0) + 32)
    # If the value is Fahrenheit, convert to Celcius
    elif selector.startswith('f'):
        print "%s degress fahrenheit is %.2f degrees celcius." \
        % (valStr, (value - 32) * 5.0/9.0)    # if the value is in inches, convert to centimetres
    elif selector.startswith('i'): # allows userInput 'in'
        print "%s inches is %.2f centimetres." % (valStr,
        value * 2.54)
# Initialize some variables
convertTypes = ('ce', 'fe', 'cm', 'in', 'c', 'f', 'i')
# Use a while loop, waiting for and empty string or 'q'
while True:
    # Prompt and read at one time
    userInput = raw_input("Enter a value to convert or q to quit: ")
    userInput = userInput.lower() # call lower() method on the whole string
    if len(userInput) < 1 or userInput.startswith('q'):
        break # break out of loop. use len() in case you use userInput[0] instead
    lineElements = userInput.split()    # split ANY whitespace - use lots of variables for debugging
    selChar, value = lineElements[0][0:2], float(lineElements[1])
    # First, make sure that you have good data to pass
    if selChar in convertTypes:
        # Then call the funtion with the data
        # This separates input checking from converting [VERY GOOD]
        convert(selChar, lineElements[1].strip(), value)
    else:
        print "can not convert that..."

Awesome! You can post using tags! That's great.
Now you have some more things to work on after you copy the pieces from my last posts.
You CAN copy and paste to and from the forum, right?
