Python Square Root Function - Learn how to use the square root function in Python with examples and explanations. Discover methods to calculate square roots effectively.
epsilon越接近0,算出的方根值就越精确。 调用此函数试一下,同时与python自带的sqrt函数进行对比: print(sqrt_bi(8)) import math print(math.sqrt(8)) 运行结果如下: 2.82842712474619 2.8284271247461903 python自带的sqrt函数比sqrt_bi函数还要更精确一些。 参考:麻省理工学院公开课:计算机科学及编程导论(第5课)...
You can solve this equation using the Python square root function: Python >>>a=27>>>b=39>>>math.sqrt(a**2+b**2)47.43416490252569 So, Nadal must run about 47.4 feet (14.5 meters) in order to reach the ball and save the point. ...
