I am newbie to python i wrote a small function which is resulting in error can you please let me know what is the mistake i am doing
def cost(input):
output=input*2
next=output*3
return output,next
print output
print next
Namerror name 'output' is not defined
Output is not defined since it is local to the function and the function hasn't even run. To get it globally, above print output you would put:
output, next = cost(1.12)
You need to call the function first. Both output and next are defined within the function and can not be accessed directly from outside.
print output
There is no variable called output for python to display. The output variable you have is inside the function, which is not accessible outside.
the problem is that the scope of the output and next variable is within the function, they cannot be referenced outside the function. If you want to print the result, just call the cost function in the print statement:
print cost(100)
output,next = cost(10)before printing output variable.
