三、把else语句放进for loop 例5:我们写一个简单的奇数偶数判别代码: 输入: for i in list(range(10,20)): if i%2 == 0: print(i,'是偶数') else: print(i,'是奇数') 系统则会输出: 10 是偶数 11 是奇数 12 是偶数 13 是奇数 14 是偶数 15 是奇数 16 是偶数 17 是奇数 18 是偶数 19 ...
The Python while loop: you'll learn how you can construct and use a while loop in data science applications. You'll do this by going over some interactive coding challenges. Next, you'll move on to the for loop: once again, you'll learn how you can construct and use a for loop in...
Be careful to not make an eternal loop in Python, which is when the loop continues until you press Ctrl+C. Make sure that your while condition will return false at some point. This loop means that the while condition will always be True and will forever print Hello World. while True: p...
Programs often have to run the same commands over and over again. Python provides two types of loop statements to handle two different situations. The Python for loop is used when the number of iterations is known before the loop starts running. In contrast, the Python while loop repeats as...

In Python, loops can be used to solve awesome and complex problems. You will likely encounter problems that would require you to repeat an action until a condition is met(while loop works best here) or a problem that requires you to perform an action on a bunch of items(for loop works ...
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 ...

for loop in C 1. while Loop in C While loop executes the code until the condition is false. Syntax: while(condition){ //code } Example: #include<stdio.h> void main() { int i = 20; while( i <=20 ) { printf ("%d " , i )...
