The range() generates the integer numbers between the given start integer to the stop integer. print("Reverse numbers using for loop") num = 5 # start = 5 # stop = -1 # step = -1 for num in (range(num, -1, -1)): print(num) Run Output: 43210 Example 3: Reverse a ...
Before we wrap up, let’s put your knowledge of Python for loop to the test! Can you solve the following challenge? Challenge: Write a function to calculate the factorial of a number. The factorial of a non-negative integernis the product of all positive integers less than or equal ton....
...因此,在声明变量时,好的方式是严格定义该变量的类型,例如: Dim lng As Long Dim intNum As Integer Dim curMon As Currency Dim str As...(msdn) 实际上,我们可以用简写符号来声明变量,对于上述代码可以进行如下声明: Dim i&, j&, count& 因为Long类型的声明字符是&。
In a for loop, the integer mentioned inside the range function is the range or the number of times the control needs to loop and execute the code in the for loop's clause. Note that the range() function's count starts from 0 and not from 1. That means that, in the above example,...
