在Python中,我们首先需要引入decimal模块,可以通过以下方式实现: fromdecimalimportDecimal 1. 引入Decimal类后,我们可以使用该类来创建具有任意精度的十进制数。 在print函数中使用Decimal 当我们需要在print函数中输出decimal模块创建的十进制数时,可以直接将Decimal对象传递给print函数。下面是一个简单的示例: fromdecimal...
The print() function is a fundamental part of Python that allows for easy console output. The function has replaced the older print statement in Python 3, providing more versatility with keyword arguments. This tutorial explains various ways to use print() for different formatting needs, string m...

programming languages vary in how much precision they allow in printed floating-point fractions. You would think they’d all be the same, allowing you to print as many decimal places as you ask for. After all, a floating-point fraction is adyadic fraction;it has as many decimal places as...
Python is an easy-to-learn yet powerful object-oriented programming language. The code written in Python language is similar to words in the English language. This makes it easier to read and understand the code. Python is a dynamically typed language; ever...
