实例
def returnSum(myDict):
sum = 0
for i in myDict:
sum = sum + myDict[i]
return sum
dict = {'a': 100, 'b':200, 'c':300}
print("Sum :", returnSum(dict))
def returnSum(myDict):
sum = 0
for i in myDict:
sum = sum + myDict[i]
return sum
dict = {'a': 100, 'b':200, 'c':300}
print("Sum :", returnSum(dict))执行以上代码输出结果为：
Sum : 600
