In Python, “for-loop” is widely used to iterate over a sequence, list, or any object. For loop avoids multiple usages of code lines to make the program concise and simple. The “One line for loop” is also the form of “for loop” which means that a complete syntax of “for loop...

In Python, we use indentation (spaces at the beginning of a line) to define a block of code, such as the body of a loop. For example, languages = ['Swift','Python','Go']# start of the loopforlanginlanguages:print(lang)print('---')# end of the for loopprint('Last statement...

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...
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] doubled_evens = [x * 2 for x in numbers if x % 2 == 0] print(doubled_evens) # 输出: [4, 8, 12, 16, 20] 优势 简洁性:相比传统的for循环和if语句,列表推导式更加简洁。
