#65570 — Python 2.7.6 help with white spaces?

[Multipart message — attachments visible in raw view] — view raw

I am having trouble figuring out how to remove spaces….

Assume variables exist for minutes and seconds. Each variable is an integer. How would you create a string in the format,

3:11

with no spaces. where 3 is minutes and 11 is seconds.


Obviously when I…

print minutes, “:”, seconds

I get 3 : 11

how can I get it to print with no spaces?   

3:11

I’m VERY new to python and coding in general and this is a question for a class I’m in for a test review.  So, the most basic answer would be appreciated.  

Thanks for any help!!

Scott

print "%d:%02d" % (minutes, seconds)

The "02" for the seconds specifier makes sure you get exactly two 
digits, with a leading zero if needed.

what exactly is the “%d:%02d”% saying?

Python uses string format specifiers similar to C's printf()

%d means, "convert an integer to a decimal string"

%2d means the same, plus, "make the result 2 columns wide"

and, finally, %02d means, "and, if it would normally be less than 2 columns, zero-pad it on the left".

So, putting that all together, we've got:

"%d" --> decimal integer
":" --> a literal ":"
"%02d" --> another decimal integer, this time zero-padded to two columns
