How to use log function in python

In python, you can use the log function in the math library to calculate logarithms. logThe function has two parameters: the first parameter is the value of the logarithm, and the second parameter is the base of the logarithm (the default is e, which is the natural logarithm). The following is sample code using the log function:

import math

# 计算以e为底的对数
result = math.log(10)
print(result)# 输出结果为2.302585092994046

# 计算以2为底的对数
result = math.log(10, 2)
print(result)# 输出结果为3.3219280948873626

In the above example, math.log(10) calculates the logarithm of base e, and the result is 2.302585092994046. math.log(10, 2)Calculate the logarithm with base 2, the result is 3.3219280948873626.
