Is there a specialist in error handling ? - sylas - May-21-2017
my question here:Please help me to finish with this file. I am a beginner and I am unable to use "try" and "except"
# file2.py
size = 40
print("here is the addition of many numbers (even with a .) Maximum of numbers=", size)
print("Once you have finished your list of numbers, just press $ to indicate the end\n")
total = 0.0
value = 0.0
count = 1
while (count != 0):
value = float(input("enter the value: "))
if value == '$':
average = total / count
print("average value= ", average)
exit()
else:
print(value)
print(total)
total = value + total
print(total)
count = count + 1

When you paste from your IDE use CTRL+SHIFT+V instead of CTRL+V to paste the code as plain text without formatting.

What have you tried? This shouldn't require a specialist, its (probably) basic error handling and you need to elaborate further on the requirements.

Here a hint:
>>> total = 10
>>> count = 5
>>> average = total / count
>>> average
2.0
>>> count = 0
>>> average = total / count
Traceback (most recent call last):
File "<string>", line 301, in runcode
File "<interactive input>", line 1, in <module>
ZeroDivisionError: division by zero
>>> # Now using try:except to catch that error
>>> try:
... average = total / count
... except ZeroDivisionError:
... print('Cannot divide by zero,try again')
...
Cannot divide by zero,try again

He said he can't use try and except. In that case, you need to do defensive programming:
if count:
average = total / count
print('The average is', average)
else:
print('Cannot divide by zero, try again.')

"Unable" could mean disallowed or failing after trying.

You seem to have posted the same question after getting two answers. If neither of those errors is helpful, you need to clarify your question.
