I have a data that has two columns time and corresponding amplitude of signal. I need to compute the frequency of the signal. How can do this. I read about scipy and numpy fft. But I really do not understand how to use them in my case.

Lift Coefficient vs Time

I need to Calculate the frequency for the signal that is after time say 4s. which seems periodic.
