ArcPy SearchCursor row format

Question

I set up a script to print some statistics about line segments. The "logfile" is basically the same as "print", but to a textfile instead of on screen only.

LogFile("Feature {0} has a length of {1} meters at coordinates {2}".format(row[0], row[1], row[2]))

This will give me an output like:

Feature 1 has a length of 346.239783695 meters at coordinates (470765.69285000017, 6313169.6829)

I want to drop the decimals (i.e., turn the values into integers for reporting purposes only) and just have

Feature 1 has a length of 346 meters at coordinates (470765, 6313169)

How do I alter the format within the script to accomplish that? I assume it will be super easy and something I should know, but I've been out of the Arc/Python world for a few years.

• PolyGeo: This is a pure Python question that I can remember researching and finding a solution for at Stack Overflow.

Answer 1

This can be accomplished by taking full advantage of the format function you're already using. In its basic form (e.g. '{0}'.format(var)), the value returned is equivalent to str(var). However, by adding stuff inside the curly braces, you can tweak the formatting quite extensively -- see PEP 3101.

For your specific example, try this:

LogFile("Feature {0} has a length of {1:.0f} meters at coordinates ({2:.0f}, {3:.0f})".format(row[0], row[1], row[2][0], row[2][1]))

I had to separate the coordinates tuple into its individual components, as the float formatting doesn't work on tuples directly.

• Jeff C: Thanks for that. I figured it was something simple. The tuple thing got me for a bit. The following also seems to work 'LogFile("Feature {0} has a length of {1} meters at coordinates ({2}, {3})".format(int(row[0]), int(row[1]), int(row[2][0]), int(row[2][1])))'
