我收到以下代码的错误:
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)))
期望输出
INFO:root:Hypotenuse of 3, 4 is 5.0
请您参考如下方法:
我很确定它唯一可行的方法是在调用之前定义变量:
a,b = (3,4)
logging.info("Hypotenuse of {a}, {b} is {c}".format(a=a, b=b, c=hypotenuse(a,b))
可能更清楚一点:
a,b = (3,4)
logging.info("Hypotenuse of {}, {} is {}".format(a, b, hypotenuse(a,b))
