The first “one line for loop” is applied on the range from “(1,6)”, and the print statement is used to print out all the elements in the specified range. In the second part, a variable named “list_1” is initialized, and the “One line for loop” iterates through the element...
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 i in range(3): if i == 2: break print(i, end=' ') # 打印0和1 else: print("Loop completed without encountering a 'break' statement.")5.循环控制语句：range()函数：生成一个起始默认为0的序列，通常与for循环一起使用。def print_numbers(n): for i in range(1, n+1): print(i)...
