I am getting error for the below code:
logging.info("Hypotenuse of {a}, {b} is {c}".format(a=3, b=4, c=hypotenuse(a,b))) NameError: name 'a' is not defined
import logging
logging.basicConfig(level=logging.INFO)
def hypotenuse(a, b):
"""Compute the hypotenuse"""
return (a**2 + b**2)**0.5
logging.info("Hypotenuse of {a}, {b} is {c}".format(a=3, b=4, c=hypotenuse(a,b)))
Desired Out
INFO:root:Hypotenuse of 3, 4 is 5.0
I'm pretty sure the only way it will work is defining the variables before the call:
a,b = (3,4)
logging.info("Hypotenuse of {a}, {b} is {c}".format(a=a, b=b, c=hypotenuse(a,b))
possibly a little clearer:
a,b = (3,4)
logging.info("Hypotenuse of {}, {} is {}".format(a, b, hypotenuse(a,b))
logging.info("Hypotenuse of {a}, {b} is {c}".format(a=3,b=4, c=hypotenuse(3,4)))
you can try :
a = 3
b = 4
logging.info(f'Hypotenuse of {a}, {b} is {hypotenuse(a, b)}')
