[Python] Pine scripts (tradingview) convert python

I have two pine scripts (tradingview). How can I the script to Pandas python or with help talib library convert and how can man ‘pds’ calculate. I donot need The plot. I well by thankful if some help

wapScore(pds) =>
mean = sum(volume*close,pds)/sum(volume,pds)
vwapsd = sqrt(sma(pow(close-mean, 2), pds) )
(close-mean)/vwapsd

plot(vwapScore(48),title="ZVWAP2-2",color=#ffe0b2, linewidth=2,transp=0.75)
plot(vwapScore(199),title="ZVWAP2-2",color=#cfb9ff, linewidth=2,style=circles,transp=0.75)
plot(vwapScore(484),title="ZVWAP2-3",color=#ffe0b2, linewidth=2,style=circles,transp=0.75)

=============================================================

study("VWAP", overlay=true)
typicalPrice = (high + low + close) / 3
typicalPriceVolume = typicalPrice * volume

cumulativePeriod1 = input(48, "Period")
cumulativeTypicalPriceVolume1 = sum(typicalPriceVolume, cumulativePeriod1)
cumulativeVolume1 = sum(volume, cumulativePeriod1)
vwapValue1 = cumulativeTypicalPriceVolume1 / cumulativeVolume1
plot(vwapValue1,color=#b2b5be,style=circles)```
