Hi there,
I'm in the process of learning Python, and need some help deciphering
the reason why the following code doesn't work:
import sys, string
def dec2bin(decNum):
# validate the input as a postive integer number
for char in decNum:
if str(char).isdigit() == False:
print "Not a postive integer number given when calling
the dec2bin
function."
sys.exit()
bin = "" # initialize the new
binary result (as a string)
num = int(decNum)
if num == 0: # take care of the zero case
bin = "0"
while int(num) != 0: # the rest of the cases
nextBin = int(num) % 2 # check if this column should
be a 0 or 1
bin = str(nextBin) + bin # add the result to the
front of the result
string
int(num) = int(num) / 2 # this is integer division, so
we truncate
the decimal part
return bin # return the
binary result
# testing
x = "13"
print dec2bin(x)
I get the following error:
> File "convert.py", line 42
> int(num) = int(num) / 2 # this is integer division, so
> we truncate the decimal part
> SyntaxError: can't assign to function call
Any help anyone can provide would be greatly appreciated.
Dan
