This loop means that the while condition will always be True and will forever print Hello World. while True: print "Hello World" Nested Loops In some script you may want to use nested loops. A nested loop in Python is a loop inside a loop. It’s when you have a piece of code you ...
A while loop looks just like an if statement; just replace the "if" keyword with the keyword "while". The statement above says that while num is equal to 3, keep executing whatever code is inside the brackets. When the bottom of the code in the brackets is reached, it goes back up ...
We can use Exit For statement inside an IF statement to exit the loop when a certain condition is met. Exit a While Loop When a Certain Condition is Met There is no statement to exit a While loop like Exit For or Exit Do.Microsoft recommends us to use the Do loops as they are more...
The message written inside the loop displays when the condition gets satisfied. If the value of a variable is equal to 4 then the loop is terminated as Exit Do statement is used at this point and the cursor will move to the next statement of Do While Loop. Hence no output is produced ...
1) boolean condition – if true, continue to next step; if false, exit loop 2) loop body 3) repeat from step 1 (boolean condition) Example – Integer Array To loop over an integer array with a while loop, we initialize a local variable to 0, which is the first array index. The bo...
While loop vs a for loop Sometimes, a while loop can be used as an alternative to a for loop. This is particularly useful when the number of iterations is not predetermined, as in the following example: i = 0 while i < 5: print(i) ...

It is very common to initialize a variable before a while loop, check that variable in the loop condition, and change that variable each time through the while loop.for loopsare a convenient shorthand that combines the initialization, condition check, and variable change in one place. The forma...
The condition for loop termination C. The value to be printed D. The type of data 相关知识点: 试题来源: 解析 A。在 for 循环中,括号里的变量通常控制循环的迭代次数。比如 for(int i = 0; i < 10; i++),这里的 i 从 0 开始,每次循环加 1,直到不满足 i < 10 的条件时循环结束,所以它...
for a in sequence: body of for The following flowchart explains the working of for loops in Python: As depicted by the flowchart, the loop will continue to execute until the last item in the sequence is reached. The body of the for loop, like the body of the Python while loop, is in...
