Python - 偷懒法
class Solution:
def Power(self, base, exponent):
# write code here
return base ** exponent

class Solution:
def Power(self, base, exponent):
# write code here
if exponent == 0:
return 1
elif exponent > 0:
res = 1
for _ in range(exponent):
res *= base
return res
else:
res = 1
for _ in range(abs(exponent)):
res *= base
return 1 / res
