Next, we used the for loop to iterate over the numbers produced by the range() function In the body of a loop, we printed the current number. for num in range(10): print(num) Run Output: 0 1 2 3 4 5 6 7 8 9 for loop with range() The range() function returns a sequence...
第一个for循环用于输出空格行,第二个for循环用于输出星号行。通过调整rows和cols变量的值,可以改变输出表格的大小。 5. 类图 下面是本文中使用的类图: Loop+loop_output_spaces_for(spaces:int)+loop_output_spaces_while(spaces:int) 6. 状态图 下面是本文中使用的状态图: Looploop_output_spaces_forloop_outpu...

For loop是一个遍历命令,意味着要把一个序列里的所有元素都循环一遍。 Python执行for loop从第一行到最后一行,exp: for question in questions: print("---") print(question) for option in options[question_num]: print(option) python会先执行print("---")然后print(question)以此类推。 2. question_nu...
