import random
a = random.randrange(0,101)
while  True:
	b = int(input("请你输入一个数:"))
	if b > a :
		print("您猜大了")
	elif b < a :
		print("您猜小了")
	else :
		print("恭喜你,猜对了")
		break

结果:

38.

a,b = eval(input("请输入两个数:"))
if a > b :
	small = b
elif b > a :
	small = a
else :
	print("最大公约数为:"+str(a))
	exit(0)
for i in range(1,small+1) :
	if a % i == 0 and b % i == 0 :
		gcd = i
print("最大公约数为:"+str(gcd))

结果：

	y = random.uniform(0,1)
	l = math.sqrt(x**2 + y**2)
	i+= 1
	if l < 1 :
		NOH+=1
pai = (NOH * 4) / 1000000
print("π的值为:"+str(pai))

结果·：

for j in range(0,i):
	pai += 1/(1+2*j)
	pai *=-1

结果：

	e = 1 / a
	a = 1
print("e的z近似值为:"+str(e))

结果：

		if i % j == 0:
			a += j 
	if a == i:
		print("10000以内完全数有:",a)
	a = 0
