Python 代码无法运行，我不知道如何修复它

Question

class AQGraph:
    import pandas as pd
    import numpy as np
    import matplotlib as plt

    PrimaryA = pd.read_csv('PrimaryA.csv')  # Daily data from 12/1/19 to 4/16/20 from PrimaryA sensor
    PrimaryB = pd.read_csv('PrimaryB.csv')  # Daily data from 12/1/19 to 4/16/20 from PrimaryB sensor
    AverageData = np.mean(PrimaryA[:][2], PrimaryB[:][2])

    print(AverageData)
    plt.plot(PrimaryA[:][0], AverageData)
    plt.show()

Attached is my python code. I'm running it in Pycharm and for some reason the green arrow that pops up for Pycharm files isn't there. I've looked through my settings and I'm running Python 3.7. Any advice?

The code you provided, doesn't comply with python rules and standards. there is a class in your code without any constructor or any method. Also, you didn't follow Python's indentation policy. Based on what you provided, as soon as you try to run it you should see an error.

import pandas as pd
import numpy as np
import matplotlib as plt
class AQGraph:

    @staticmethod
    def a_method():

        PrimaryA = pd.read_csv('PrimaryA.csv')  # Daily data from 12/1/19 to 4/16/20 from PrimaryA sensor
        PrimaryB = pd.read_csv('PrimaryB.csv')  # Daily data from 12/1/19 to 4/16/20 from PrimaryB sensor
        AverageData = np.mean(PrimaryA[:][2], PrimaryB[:][2])

        print(AverageData)
        plt.plot(PrimaryA[:][0], AverageData)
        plt.show()


if __name__ == "__main__":
    AQGraph.a_method()

In the command line try:
