Python开发【第一篇】基础题目

n = 1
s = 0
while n<100:
    temp = n%2
    if temp == 0: #偶数
        s = s-n
    else:
        s = s+n
    n = n+1
print(s)

n = 1
s = 0
while n < 101:
    s = s+n
    n = n+1
print(s)

#一行代码搞定
print (sum(range(101)))

for i in range(1,10):
    for j in range(1,10):
        if i>=j:
            print("%s * %s == %s"%(j,i,i*j),end="\t")
    print("")
