The following shows an example of using the log () method:
#!/usr/bin/python3
import math # 导入 math 模块
print ("math.log(100.12) : ", math.log(100.12))
print ("math.log(100.72) : ", math.log(100.72))
print ("math.log(math.pi) : ", math.log(math.pi))
After running the above example output is:
math.log(100.12) : 4.6063694665635735 math.log(100.72) : 4.612344389736092 math.log(math.pi) : 1.1447298858494002
