Definite Iteration: When we know how many times we wanted to run a loop, then we use count-controlled loops such as for loops. It is also known as definite iteration. For example, Calculate the percentage of 50 students. here we know we need to iterate a loop 50 times (1 iteration fo...
例如,我们可以定义一个函数来打印学生的信息: def print_student_info(name, age, gender):(tab)print("Name:", name)(tab)print("Age:", age)(tab)print("Gender:", gender) 1. 调用print_student_info(name=“Alice”, age=25, gender=“Female”)将输出: Name: AliceAge: 25Gender: Female 1. ...

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)...
print(index) ... 0 1 2 3 4 In these examples, you iterate over a tuple, string, and numeric range. Again, the loop traverses the sequence in the order of definition.Note: For more information about tuples, strings, and ranges, you can check out the following tutorials: Python’s tu...
理解Python 中的 for 循环 Review: Python’s for loop Python 中的 for 循环不是传统的 for 循环。为了解释我的意思,我们来看一下其他语言的 for 循环是怎么写的。...没有索引初始化、边界检查和索引增加。Python 的 for 循环都把这些工作为我们做了。 所以在 Python 中确实有 for 循环,但不是传统的 C...

使用index() 方法查找索引; 使用for-loop; 使用列表推导式和enumerate() 函数 Python 列表是什么? 列表是Python中的内置数据类型,也是最强大的数据结构之一。它可以充当容器,用于存储相同变量名下的多个(通常是相关的)项。每一个元素都被放置在方括号 [] 内,方括号内的每一项都用 , 隔开。 从上面的示例中,你...
