I have two integer b,n. I need to check if the number n is integer power of number b. For example: 100 is an integer power of 10. As 10^2 = 100. But 110 is not an integer power of 10. How to determine this in coding?

I am a beginner in python. I've solved problems in some OJs with C++. Now i want to do it with Python 3. I started but i saw that my code wasn't not efficient. I got run time error or Time Limit. I faced problems taking input specially in UVa problems. Please help me.

My Code:

from sys import stdin,stdout
dd = dict()
tests = int(input().strip() )
for t in range(tests):
dd.clear()
sm = 0.0
m = int(input().strip())
for x in range(m):
ch,vl = input().strip().split()
dd[ch]=float(vl)
for x in range(int(input())):
line=input()
for letter in line:
if letter in dd:
sm += dd[letter]
print('%0.2f\$' %(sm/100.0))
