Python - Variable being printed over string

Question

I am using python 2.7 and i have a problem that i haven't encountered before, when i print a certain string and then a variable on the same line the variable is printed over the string. e.g. the script is coded like so print 'IP Rating = ', ipRating and the output in command prompt will be 'IP20ating = '. I have no idea why this is happening but i have the same code for various variables and string in the same script and they all come out as expected, i have tried renaming the variable and changing the string but there is still no difference, has anybody encoutered this error before or have any ideas why this might be happening? i can post the code if requested. Many thanks :)

EDIT Here is the code - I know i may have repeated myself a few times and there are unneccessary library's in there but the way i work is by importing all libraries i might need and then removing unnecessary code at the end.

Here is an example output

IP44ating =
Weight =  .51KGS
Projection =  35 mm
Diameter =  0 mm
Length =  0 mm
Height =  90 mm
Width =  120 mm

Please post the code, and you could give this a try: print 'IP Rating = ', str(ipRating) — Trygve
– Trygve, Commented Mar 11, 2014 at 12:15
so you are saying that ipRating variable has the value 20, but when printed you get 'IP20ating = '.. right?? — Srivatsan
– Srivatsan, Commented Mar 11, 2014 at 12:16
theres the code,@Trygve the variable has already been formatted as a string, would reformatting it make a difference? and @Srivatsan thats exactly what happens except the ipRating variable is not always 20 — user3223643

I strongly suspect that your data ipRating that you think is IP20 is actually \rIP20. That is: that you have a stray 0x13 carriage return character in there at the start of the variable. The carriage return character is moving the print position to the start of the line and then the variable is overwriting what you printed before.

You can test whether this is the problem by adding the line:

ipRating = ipRating.replace("\r", "")

before your print statement.

I'll try this now and let you know the output

Good. You should try to work out where the stray character is coming from, however, rather than simply papering over the cracks.

This is the proper way to do what you're doing.

print('IP Rating = %s' % ipRating)

or

print('IP Rating = %d' % ipRating)

That is just one example from all the print statements you have at the end of your code.

If you're putting a string variable in print, use a %s or otherwise use a %d. If you have any more questions just ask.

he is using Python 2.7

This was done on Python 2.7 guys. It supports function based printing as well.

CasualDemon Over a year ago

If you are going to suggest changing to the print function, wouldn't it also make sense to change to the format function? print('IP Rating = {0}".format(ipRating))

user3223643 Over a year ago

@Remolten Same output, thanks for the advice and the help though

user3223643 Over a year ago

@CasualDemon same output, damn this is frustrating haha
