By using wave in Python we can read .wav audio format and can calculate the frequency and power of a signal. But I want to calculate the frequency of .mp3 audio format directly. I've heard a little bit about Pysox. Is Pysox capable of reading frames and can we calculate the fft and frequency using Pysox? Or is there any other software which can calculate the frequency of an MP3 file using Python?

your questions has a few parts, but I'll give it a shot: you can get the raw audio data using pydub (the same thing the
wavemodule gives you)(note that you'll need ffmpeg or avlib installed for the mp3 decoding)
From there you should be able to use numpy. This O'Reilly post may also help
