How to use the log function in Python?

In Python, you can use the log function by using the log function from the math module. Here is how you can use it:

import math

# 计算以e为底的对数
result = math.log(x)

# 计算以指定底数为底的对数
result = math.log(x, base)

Here, x represents the value for which the logarithm is calculated, and base is the specified base. If the base is not specified, it defaults to e (natural logarithm).
