numbers = list(range(5)) print(numbers) # 输出: [0, 1, 2, 3, 4] 检查序列中的数值: 可以使用 in 关键字来检查一个数字是否在 range() 生成的序列中。 if 3 in range(5): print("3 is in the range") # 输出: 3 is in the range 迭代列表的索引: 结合len() 函数,可以使用 range() ...
If you do need to iterate over a sequence of numbers, the built-in function range() comes in handy. It generates arithmetic progressions:如果你需要迭代一个数字序列，内置函数Range（）就方便了。它产生算术级数序列：>>> for i in range(5):... print(i)...0 1 2 3 4 The given end po...
Create integers and floating-point numbers Round numbers to a given number of decimal places Format and display numbers in stringsLet’s get started!Note: This tutorial is adapted from the chapter “Numbers and Math” in Python Basics: A Practical Introduction to Python 3. If you’d prefer a...
If you do need to iterate over a sequence of numbers, the built-in function range() comes in handy. It generates arithmetic progressions --有道翻译的结果:如果确实需要迭代一组数字,那么内置函数range()就派上用场了。它生成算术级数。 3、实例调用 ...
range is a sequence of numbers. range (num) is a sequence of integers from 0 to num (without num), such as range (4), which is {0, 1, 2, 3}; range (num1, num2) is a sequence of integers from num1 to num2 (without num), such as range (2,5), {2,3,4}; range (num...
编写一个Python函数,接收一个整数列表作为参数,返回列表中所有偶数的平均值。```pythondef average_even(numbers):evens = [x for x in numbers if x % 2 == 0]if len(evens) == 0:return 0return sum(evens) / len(evens)numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]print(a
编写一条if 语句, 检查外星人是否是绿色的; 如果是, 就打印一条消息, 指出玩家获得了5个点。 编写这个程序的两个版本, 在一个版本中上述测试通过了, 而在另一个版本中未通过(未通过测试时没有输出) 。 5-4外星人颜色#2: 像练习 5-3那样设置外星人的颜色, 并编写一个if-else 结构。
