I've heard about using assert() to check up
The top three work silently, but I found that I could not figure
out how to use assert() with the functions that print rather than
return. E.g., maxDiffBetPrimes() and printTime(). Is there a way?
Thats another good reason for not printing inside functions.
Just get them to return the pre formatteed string which can
be printed outside the function.
Unless you have a value to check you can't really use assert()
So if the function uses globals (which it shouldn't!) you might
check them otherwise you are stuck.
If it'll help, here's printTime():
def printTime(timeEnd, timeStart):
from mycalc import hmsToText
timeElapsed = timeEnd - timeStart
if timeElapsed > 60:
print "Time was", hmsToText(timeElapsed)
else:
print "Time was %.4g seconds" % timeElapsed
Replace the prints with returns
change the function name to getTime()
Then call it with
t = getTime(...)
print t
Now you can use an assert on t...
Of course if getTime is not your functin then
modification may not be possible!
