Question

I have the following code and I am trying to iterate across values during a search and then append to the values.

for delvt, pin in zip(temp_delvt_list, temp_pin_list):
    temp[delvt].append(pin)
    print temp
SPFFile = open(pathSPFfiles + temp_cell + ".spf", "r")
for line in SPFFile:
    for pin in temp[delvt]:
         print pin

Output of temp is:

defaultdict(<type 'list'>, {'0.1995': ['in1', 'in2'], '0.399': ['in0', 'y']})

Output of pin is only:

in0
iny

Why is pin not outputting in1 and in2 also?

Answer 1

Because you’re outside of the loop that changes delvt, hence you only use the last assigned value.
