Cleverly taking advantage of Python’s built-inordfunction to get theASCII codeof lower case ‘e’ (it is 101 not 100), we sort of have a code-golf winner. Sort of because it starts count from 0 not 1 as the original question posed. But this is Twitter, a correction soon emerged. ...
The simplest way to find and print prime numbers from 1 to N in Python is by using basic iteration and checking for each number’s divisibility. Let me show you an example and the complete code. Example: Here is the complete Python code to print prime numbers from 1 to n in Python. ...

sieve=[True]*101foriinrange(2,100):ifsieve[i]:print(i)forjinrange(i*i,100,i):sieve[j]=False 输入这段代码时,VSCode 自动缩进了 for 和 if 下的语句,自动加上了结尾大括号,并为你提供输入建议。这就是 IntelliSense 的威力。 运行Python 代码 既然写完了代码,我们就可以运行它了。因为 VSCode 可...
