Python label expression adding text & fields

DamonOsbourne — Fri, 06 Jul 2018 14:08:49 GMT

Need python label expression to label linear assets in Arcmap 10.3 with length (rounded to nearest whole number) with a foot symbol(') at the end, plus a space, then text from a different field. Have this so far: round(float( [LLENGTH]), 0)

don't know about 10.3 or vb but in python and recent versions

leng = 7.4

fld = 'from field'

result = "{}' {}".format(round(leng), fld)

print(result)

7' from field‍‍‍‍‍‍‍‍‍

Thanks, I may have tagged the question incorrectly, looking for label expression syntax for the Maplex Label Engine in Arcmap

Damon,

Dan has given the correct Python Label Expression in line 5 of his example. The first variable will be the LENGTH field, and the second is whatever other text field you chose.

You may have to convert the length field to a float first (line 3).

"{}' {}".format(round(leng), fld)‍

"{}' {}".format(round(float(leng)), fld)‍‍‍‍‍‍‍
