All,
I have been going in circles trying to format a floating point number so
there is only 1 decimal place. In reading all of the gobble-gook that
passes for Python advice, it looked like I should have done this:
numStr = '3.14159'
num = float(numstr) # OK so far
numFmt = format(num, '{0:.1f}') # Errors on format string
# --- Alternative that also does not work
numFmt = float("{0:.1f}".format(numStr))
# ---
numFmt = format(num, '0.1f') # Does work
My question is why, and where do I find a reliable source of information
on formatting numbers? Not interested in replacement values like '{}
{}'.format(1, 2).
Thanks,
Dave
