# TODO: Loop through all 50 states, making a question for each. 因为这个程序会随机排序问题和答案,你需要导入random模块➊ 来使用它的函数。capitals变量➋ 包含一个字典,以美国各州为键,以它们的首都为值。由于您想要创建 35 个测验,实际生成测验和答案文件的代码(现在用TODO注释标记)将进入一个for循环...

In the second part, a variable named “list_1” is initialized, and the “One line for loop” iterates through the elements of “list_1”. Output The numbers are printed from “1 to 5,” using the first “one line for loop”. And the characters “b a s h” are printed with the...
We use the exec() function to dynamically execute a nested for loop, iterating through all combinations of elements from listOne and listTwo. Inside the loop, we print the sum of each pair (a, b) using the print(a + b) statement. Now, let’s have another example using the .join()...
In this tutorial, we'll be reading a file line by line in Python with the readline() and readlines() functions as well as a for loop - through hands-on examples.
>>> 1 / 0 Traceback (most recent call last): File "<stdin>", line 1, in <module> ZeroDivisionError: division by zero >>> one_more_func() Iteration 0💡 Explanation:When a return, break or continue statement is executed in the try suite of a "try…finally" statement, the finally...
Python provides various ways to writing for loop in one line. For loop in one line code makes the program more readable and concise. You can use for
Method 1: Single-Line For Loop Just writing thefor loopin a single line is the most direct way of accomplishing the task. After all, Python doesn’t need the indentation levels to resolve ambiguities when the loop body consists of only one line. ...
