如果给定一个list或tuple,我们可以通过for循环来遍历这个list或tuple,这种遍历称为迭代(Iteration)。迭代是通过for ... in来完成的。 list这种数据类型虽然有下标,但很多其他数据类型是没有下标的,但是,只要是可迭代对象,无论有无下标,都可以迭代,比如dict就可以迭代。 03 库的学习 numpy import numpy as np 1....
python题目 Write a function that computes and returns the sum of the digits in an integer. Use the following function header: def sum_digits(number): For example sum_digits(234) returns 9. Use the % operator to extract the digits and the // operator to remove the extracted digit. For...
1.3 不定长参数 在Python 函数中,还可以定义可变参数。顾名思义,可变参数就是传入的参数个数是可变的,可以是1 个、2 个到任意个,还可以是0 个 def sum(*num): total = 0 for n in num: total += n return total sum(1) # 1 sum(2,3,4,5,6) # 20 sum() # 0 在定义函数时,在参数名前...
