I am a beginner and I have a question of syntax.
I am just learning to use list comprehension, which oc course, I find
very helpful indeed.
However, I am stuck with a specific problem of how to incorporate an
else in a list comp-rehension. I cannot do it.
The following snippet of code does what I need. But, perhaps I am
solving this math error problem incorrectly.
The problem is I am occasionally getting exactly zeros when I need to
obtain the logarithm of the number.
for i in range(len(cap)):
if cap[i] == 0.0:
tmp = math.log(1.0)
lncap.append(tmp)
else:
lncap.append(math.log(cap[i]))
I have set mu options to plain text.
