Integer division in python may result in 0 and the following error may be thrown
I wrote a note on how to deal with it.
# xxx is some variable ValueError: xxx must be > 0
By default Python outputs 0 if the numerator is greater than the denominator.
As a workaround, it seems that the calculation result with a decimal point can be obtained by specifying to handle it as a float type or by multiplying it by 1.0 as shown below.
# The output is int type, no problem. >>> 10/10 1 # There is a problem if the output is int type. >>> 10/100 0 # A pattern that specifies handling in float type and sets the output to float type. >>> float(10)/100 0.1 # A pattern that multiplies by 1.0 and makes the output a float type. >>> 10*1.0/100 0.1 # By the way, in the following, the output of the calculation result 0 is converted to float type, so it becomes "0.0". >>> float(10/100) 0.0No tags for this post.
