Wrapping statements in Python in SPSS

[alankrinsky]

I am working with Python looping in SPSS. What are the limits for the

for var1, var2, var3 in zip(Variable1, Variable2, Variable3):

statement in the Python looping function within SPSS? I am getting an errormessage, I presume because of wrapping or length. Imagine the above statement, but expanded, as I am working with more than 28 variables in this loop, and even making the names really short is making the statement too long. Is it impossible to wrap and make this work? I know there are ways to wrap strings, including lists of variables, but here I have a statement/function..

Thank you for any help!

At what point are you wrapping it? Can you show the wrapped form and
the error message?

As a general rule, you can safely wrap anything that's inside parentheses.

for (
var1,
var2,
var3
) in zip(
Variable1,
Variable2,
Variable3
):
pass

That may be a tad excessive, but you get the idea

Chris,

I tried placing in the format you suggested and received this error message:

END PROGRAM.
Traceback (most recent call last):
File "<string>", line 396, in <module>
ValueError: incomplete format key

You seem to have a malformed format string. Example:

Correct:
'Wonderful Spam'

Broken (not the missing ')'):
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: incomplete format key

Chris,

I tried placing in the format you suggested and received this error message:

END PROGRAM.
Traceback (most recent call last):
File "<string>", line 396, in <module>
ValueError: incomplete format key

I don't think the code I gave could produce that. You'll need to show
a bit more of your code, including at least line 396, possibly some
context. Unless one of the other members here has a working crystal
ball - mine's cooling down after excessive use.

I think 396 just comes from the end of the Python loop, without indicating which line in the loop is at issue.

Here is the full code from this section of the loop:


for (
msr, brk, dmn, src, dspd1, dspd2, dspd3, dspd4, dspd5, dspd6, dspd7, dspd8, dspd9, dspd10, dspd11, dspd12,
period1, period2, period3, period4, period5, period6, period7, period8,period9, period10, period11, period12
) in zip(
Measure, BreakVariable, Dimension, Sources, DimensionSourceTimeFrame1, DimensionSourceTimeFrame2, DimensionSourceTimeFrame3, DimensionSourceTimeFrame4,
DimensionSourceTimeFrame5, DimensionSourceTimeFrame6, DimensionSourceTimeFrame7, DimensionSourceTimeFrame8, DimensionSourceTimeFrame9,

By the way, when lines run so long they can get hard to manage, edit,
understand, et cetera. You should consider setting things up cleanly
before doing the loop and using a list of names for columns like so:


def main():
l1, l2 = [1,2], [3,4]
zipped = zip(l1, l2)
colnames = "first second".split()

for columns in zipped:
coldict = dict(zip(colnames, columns))
print("coldict", coldict)

main()


This produces output:

coldict {'second': 3, 'first': 1}
coldict {'second': 4, 'first': 2}

... and then you can pass the coldict on to your string.

Should really be 'for column in zipped:' !

Doh - the code is good, but I got a little confused with variable names.
This should be more like it:

def main():
c1, c2 = [1,2], [3,4]
zipped = zip(c1, c2)
colnames = "first second".split()

for values in zipped:
valdict = dict(zip(colnames, values))
print("valdict", valdict)

main()


-m
