Reading and application of Python data

The document given is the three-phase voltage of a factory 、 electric current 、 power factor 、 Active power 、 Reactive power and apparent power , Read 30 Minute data , According to the voltage 、 Current and power factor , Calculate the active power 、 Reactive power 、 Apparent power , Comparison with measured data , Draw and compare the calculated value with the measured value .
explain ：
txt File data is processed data , Delete the space after reading , Transformation format ; Some documents are garbled at first , You can delete ;
voltage .txt、 electric current .txt and PF.txt The data of the file is A、B、C、N Phase voltage 、 electric current 、 Minimum value of power factor 、 Average and maximum , Use the average to calculate ;
Active power .txt、 Reactive power .txt、 Apparent power .txt The data of the file is A、B、C Minimum value of total power of phase and three phases 、 Average and maximum ;
