With Python, you can use while loops to run the same task multiple times and for loops to loop once over list data. In this module, you'll learn about the two loop types and when to apply each.Learning objectives After you've completed this module, you'll be able to: Identify when ...
Both loops can include nested loops, and you can use the continue and break statements to control the flow within them. Understanding these differences will help you choose the appropriate loop for your specific needs in Python programming.

You'll learn more about the difference between while and for loops in a bit, but for now, concentrate on the following pieces that you need in order to create a for loop: The for keyword A variable The in keyword The range() function, which is an built-in function in the Python libr...
for j in range(3): print(f"i: {i}, j: {j}") if i == 1 and j == 1: return print("内层循环结束") nested_loops() print("外层循环结束") 在这个例子中,当i和j都等于1时,return语句会终止函数的执行,从而跳出所有嵌套循环。

While Loops in PythonKhan Academy
Python’s for loops are quite flexible and powerful, and you should generally prefer for over while if you need to iterate over a given collection. However, translating the for loop into a while loop, like above, gives you even more flexibility in how you handle the iterator. Remove ads ...

In Python, you can use the break statement to exit a loop when a certain condition is met. This helps prevent infinite loops and allows for more control over loop execution. Emulating the Do-While Loop in Python In some programming languages, a "do-while" loop ensures that the code within...
