This article mainly introduces the python how to achieve logarithmic operation related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe that everyone after reading this python how to achieve logarithmic operation article will have a harvest, let's take a look at it.

1. Only take the logarithm of a single number import mathmath.log (2) # default to e as base math.log (4) # base 2, logarithm of 4

That is, math.log (c) # calculates the logarithm of c with b as the base.

2. Find the logarithm as a whole

A numpy package is required to logarithm a sequence of numbers

Import numpynumpy.log ([2pr 4p8]) # takes logarithm numpy.log2 ([2pr 4p8]) # with e as the base, and takes logarithm for 2p4p8 with 2 as the base.

That is, numpy.loga (b) # takes the logarithm of the number in the logarithm sequence b with an as the base.

Or adopt a circular body:

Import mtahl = [] for i in [2jin4pr 8]: l.append (math.log (iPower2)) # find the base 2 logarithm of every number in list

Add: python how to find the exponent and logarithm of the array

Index:

Math.exp () can only calculate the index of one number, but not the array in batches.

Numpy.exp () can calculate the index not only for a number, but also for an array in batches.

Logarithm:

Math.log ()

Numpy.log ()

The function is the same as above
