For example, say that you want to implement a number-guessing game. You can do this with a while loop: Python guess.py from random import randint LOW, HIGH = 1, 10 secret_number = randint(LOW, HIGH) clue = "" #
2. while 循环 类似于 C/C++、Java 等其他主流语言,while 一般用于重复执行一系列操作或者等待某个特定条件的达成。基本语法也差别不大,如下: while boolean_expression: statement(s) 1. 2. while 的简单例子: # Simple Example for Python While Loop a = 4 i = 0 while i < a: print(i) i += 1...
while 的简单例子: # Simple Example for Python While Loop a = 4 i = 0 while i < a: print(i) i += 1 执行与输出: while 和 break 的例子: # While Loop with Break a = 4 i = 0 while i < a: print(i) i += 1 if i > 1: break 执行与输出: while 和continue 的例子: # Whi...
This while loop will run forever, because 1 is always true. Therefore, we will have to make sure there are conditions to break out of this loop; it will never stop on its own. Our first if statement checks to determine if the variable i is between 1 and 9; if it is, we will add...
Nested while Loop in Python for loop inside While loop When To Use a Nested Loop in Python? What is a Nested Loop in Python? A nested loop is a loop inside the body of the outer loop. The inner or outer loop can be any type, such as awhile looporfor loop. For example, the out...
For example: while 1 == 1 + 1 - 1: print("And ever…") Copy There are, however, a number of uses for intentionally created infinite loops. Tip If you find yourself stuck in an infinite while loop in Python REPL, the keyboard shortcut Ctrl + C can help. It will send a stop...
While all new process are created with the same system calls, the context from which the system call is made is different. The run() function can make a system call directly and doesn’t need to go through the shell to do so:In fact, many programs that are thought of as shell ...

Example of while Loop in Python Here is the example code that uses the while Loop in Python. Python count =0 whilecount<5: print(count) count +=1 Output: 0 1 2 3 4 Explanation: Here, the while loop repeats the code block until the count variable is less than 5. During each iterat...
while True: value = yield # 接收外部发送的值 print(f"接收到: {value}") coro = coroutine_function() next(coro) # 激活协程 coro.send("Hello") # 输出: 接收到: Hello coro.send("World") # 输出: 接收到: World 1. 2. 3. 4. ...
