iterating throught a list 遍歷列表
iterating over a list 遍歷列表
有兩個(gè)方法
1.for item in list:
print item
2.for i in range(len(list)):
print list[i]

1.定義 total,變量 numbers,it will be a list
2.在function中，創(chuàng)建一個(gè)變量result and set it to zero
3.遍歷the numbers list
4.for each number,add it to result
5.finally,return result
n =[3,5,7]
def total(numbers):
result = 0
for item in range(len(numbers)):
result = result + numbers[item]
return result

n =[3,5,7]
def total(numbers):
result = 0
for item in numbers:
result = re
