In mathematical operations, if there is no calculator, we have to spend a lot of time calculating the multiplication of very large numbers, and it is very troublesome to recalculate once mistakes are made. In fact, for the multiplication of numbers, there is no need to rely on a calculator at all. There are many ways to do accurate and simple operations, namely logarithm and exponent. They solve the complex calculation of multiplication of large numbers or minimal decimals. In python, there is another way to calculate logarithm, which is the log function. This paper will introduce the statements, parameters and return values of log function, and demonstrate the process of calculating logarithm with log function with examples. Log () function: returns the natural logarithm of x, that is, returns the logarithm of x based on 2.
Python was designed by Guido Van Rossum of the Netherlands Institute of Mathematics and Computer Science in the early 1990s as a substitute for a language called ABC. Python provides efficient high-level data structures and can also be used for simple and effective object-oriented programming. Python's syntax and dynamic types, as well as the nature of explanatory language, make it a programming language for writing scripts and developing applications quickly on most platforms. With the continuous updating of the version and the addition of new language functions, it is gradually used for the development of independent large-scale projects. Python interpreters are easy to extend, and new functions and data types can be extended by using C language or C++ (or other languages that can be called through C). Python can also be used as an extension language in customizable software. Python's rich standard library provides source code or machine code suitable for all major system platforms.
