The for loop and while loop are two different approaches to executing the loop statements in python. They both serve the same functionality of looping over a python code till a condition is being fulfilled. For loops and while loops differ in their syntax. In while loops, we have to mention...
Anytime you have need to repeat a block of code a fixed amount of times. If you do not know the number of times it must be repeated, use a “while loop” statement instead. For loop Python Syntax The basic syntax of the for loop in Python looks something similar to the one mentioned...
In such cases, use a while loop. Fixed number of times: Print the multiplication table of 2. In this case, you know how many iterations you need. Here you need 10 iterations. In such a case use for loop. for loop in Python Syntax of for loop for i in range/sequencee: statement ...

A while loop in Python repeatedly executes a target statement as long as a given condition is true. The syntax of a while loop is straightforward: while condition: # execute these statements Powered By Here's a basic example: number = 0 while number < 5: print(f"Number is {number}")...
For loops are used in Python when the size of a sequence can be determined at program runtime. Otherwise, a Python while loop is usually used. Tip Learn how to program in Python with our Python tutorial! What’s the difference between the for loop in Python and other languages? Many...
for 语句后要加冒号:，也就是是改成如下有正确了 for i in (1,10):代码示例说明:for i in (1,10): print(i)输出结果是：110(1,10)代表元组，包含的元素是1和10，如果你需要的是从1到10，那么你的语句就要改成如下：for i in range(1,10): print(i)输出结果：123456789 你的...
是不是错误是这样的：按照这样就可以了：你要是想直接输出，就不能用这样了：可以试试 Ipython 你
As with Boolean operators, Python favors readability by using common English words instead of potentially confusing symbols as operators.Note: Don’t confuse the in keyword when it works as the membership operator with the in keyword in the for loop syntax. They have entirely different meanings. ...
