在Python中,函数运行到return这一句就会停止,因此可以利用这一特性,将功能写成函数,终止多重循环,例如 def work(): for i in range(10): for j in range(10): if i+j > 5: return i,j print work() 1. 2. 3. 4. 5. 6. 7. 8. 利用笛卡尔积 这种方法的思路就是,既然可以跳出单循环,我就将...

我目前正在Jupyter笔记本中使用python3,我刚刚遇到一个关键字exit。这个关键字做什么?1234 with open("some_file.txt") as f: for lines in f: print(lines) exit相关讨论 在Jupyter/Ipython中撤销我的重复关闭,因为显然这在Jupyter/Ipython中的行为不同。 那是不是江户记1〔0〕中朱庇特所特有的东西?在...
例1: break跳出while死循环 ```python while True:print("123")break print("456")###例2: break是终⽌本次循环,⽐如你很多个for循环,你在其中⼀个for循环⾥写了⼀个break,满⾜条件,只会终⽌这个for⾥⾯的循环,程序会跳到上⼀层for循环继续往下⾛>```python for i in range(5...
