Loop（循环）：重复执行一段代码的过程。Condition（条件）：用于判断代码执行的条件。Statement（语句）：一行完整的代码。Import（导入）：引入其他模块或库的功能。Print（打印）：将结果输出到控制台。二、数据类型单词：Integer（整数）：表示整数值的数据类型。Float（浮点数）：表示带有小数点的数值。String（字符串...
Loop就是我们的Loop语句,和asdl文件中设计的一样,它只有一个body,包含多个stmt,比如AugAssign和Expr,分别对应n += 1和print(n)。 6. 在Python/ast.c文件中第802行添加如下代码 caseLoop_kind:ret=validate_body(state,stmt->v.Loop.body,"Loop");break; 在之前的系列文章中是没有这一步的,因为这是一个...
The code example creates a generator function that yields random integers. With theforloop we generate five random integers. $ ./for_loop_custom_iterable.py 14 43 53 44 70 Python for loop with break Thebreakstatement terminates theforloop. for_loop_break.py #!/usr/bin/python import random ...
The break statement, like in C, breaks out of the innermost enclosing for or while loop.Python中断语句与C语言类似，打破了最小封闭for或while循环。Loop statements may have an else clause; it is executed when the loop terminates through exhaustion of the list (with for) or when the condition ...
We can use break statement to terminate the for loop if an odd number is present. We can print the sum in the else part so that it gets printed only when the for loop is executed normally. defprint_sum_even_nums(even_nums):total=0forxineven_nums:ifx%2!=0:breaktotal+=xelse:print...
Within the loop is also aprint()statement that will execute with each iteration of theforloop until the loop breaks, since it is after thebreakstatement. Let’s place a finalprint()statement outside of theforloop to know when you are out of the loop. ...
循环语句 (Loop statement)又称重复结构,用于反复执行某一操作,面对大数量级的重复运算,即使借助计算机,也会比较耗时。 循环语句一般都与条件控制语句搭配使用,根据循环判断条件的返回值,决定是否执行循环体,条件控制语句的相关内容请阅读文章。 循环有两种模式,一种是条件满足时执行循环体,称为当型循环;一种是在条件...

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)...
