Python While Loop Examples Let us take a look at a few examples of while loop in Python so that you can explore its use easily in your program. 1. Printing a range of numbers in Python number = 0 while number <=5: print(number) ...
Enter a number :20 You entered: 20 Enter a number :29 You entered: 29 Enter a number :3 You entered: 3 Enter a number :11 You entered: 11 Enter a number :22 You entered: 22 Enter a number :Traceback (most recent call last): File "examples\test.py", line 5, in num = int(...
Python编程语言的 while循环的语法 - while expression: statement(s) 在这里,语句(statement(s))可以是单个语句或均匀缩进语句块。条件(condition)可以是表达式,以及任何非零值时为真。当条件为真时循环迭代。 当条件为false,则程序控制流会进到紧接在循环之后的行。
File "examples\test.py", line 5, in num = int(input("Enter a number :")) KeyboardInterrupt 上面的例子将进入无限循环,你需要使用CTRL+C退出程序。 循环使用else语句 Python支持将else语句与循环语句相关联。 如果else语句与for循环一起使用,则else语句将在循环已用尽列表迭代时执行。
2.2 Examples Example 1:Let’s specify only the stop parameter in the range() function. # range() with stop parameter i=0 while i in range(10): print(i,end=" ") i=i+1 # Output: # 0 1 2 3 4 5 6 7 8 9 Here, we specified stop as 10. So it will return the values starti...
