1、实现1-100的所有的和
#!/usr/bin/env python
sum = 0
for i in xrange(1,101):
sum += i
print(sum)
2、实现1-500所有奇数的和
#!/usr/bin/env python
l = [i for i in xrange(1,501) if i%2 != 0]
sum = 0
for i in l:
sum += i
print(sum)
3、求1+ 2! + 3! + 4! + ……20！的和
#!/usr/bin/python
def fac(x):
mul = 1
for i in range(1,x+1):
mul *= i
return mul
sum = 0
for i in range(1,21):
sum += fac(i)
print(sum)
4、对指定一个list进行排序：[2,32,43,453,54,6,576,5,7,6,8,78,7,89]
>>> li = [2,32,43,453,54,6,576,5,7,6,8,78,7,89] >>> li.sort() >>> li [2, 5, 6, 6, 7, 7, 8, 32, 43, 54, 78, 89, 453, 576]
5.复习字典排序，字符串， list， tuple常用方法
