In a while loop, we increment or decrement the value separately. For example, 1 2 3 4 5 6 x = 7 while x>0: print (x) x -= 1 Output: 7 6 5 4 3 2 1 Conclusion In this tutorial, different ways by which we can decrement the for loop in Python have been discussed. Decreme...
冒号最常用于 if、elif、else、while 和 for 语句以及函数定义(以 def 关键字开头)的末尾。 | | 定义 addTwoNumbers(a,b):"将两个数相加"返回 a + b | 在本例中,引号中的文本是一个 docsctring。这个文本是一个帮助(addTwoNumbers)命令在交互式解释器中显示的内容。 | | 如果 long_var 为真&& \...

正如你所看到的,使用工作表的cell()方法并传递它row=1和column=2会得到单元格B1的Cell对象,就像指定sheet['B1']一样。然后,使用cell()方法及其关键字参数,您可以编写一个for循环来打印一系列单元格的值。 假设您想从 B 列开始,打印每个奇数行的单元格中的值。通过为range()函数的step参数传递2,可以从每隔一...
Using Python for loops with the range() function: Example: We can simply use Python For loop with the range() function as shown in the example below. Python 1 2 3 for i in range(2,10): print(i) Output: 2 3 4 5 6 7 8 9 By default, the increment in the range() function ...
4. Iterate List using For Loop to Get Values in Backwards You can use range() function along with the len() function to get the loop iteration in the backward direction. You can specify a range with starting valuelen(list) -1, ending value-1, and incrementing value-1to help by gettin...
# Take user input number = 2 # Condition of the while loop while number < 5 : print("Thank you") # Increment the value of the variable "number by 1" number = number+1 Powered By Thank you Thank you Thank you Powered By The code example above is a very simple while loop: ...
英文: Next, you can have nested loops just as you have nested if. Loops are used to perform iterations by repeating the execution of a piece of code multipie times. You can also perform another loop within a loop. And you can perform a while loop within a For loop, or for that matt...
