** numpy.pmt (rate, nper, pv, fv, when = & # 39; end & # 39;) : ** this financial function helps the user to calculate the interest rate for period.

Parameters:

nper:[scalar or (M,) array] total compounding periods

pmt:[scalar or (M,) array] Payment

fv:[scalar or (M,) array] Future value

pv:[scalar or (M,) array] present value

when:at the beginning (when = {`begin`, 1}) or the end (when = {`end`, 0}) of each period. Default is {`end`, 0}

Return:Rate of interest per period.

** The equation is being solved: **

fv + pv * (1 + rate) ** nper + pmt * (1 + rate * when) / rate * ((1 + rate) ** nper - 1) = = 0

or

when rate == 0

fv + pv + pmt * nper == 0

** Code: **

** Exit:**

Solution = rate -2.024705182882783
