python – I tried to predict using simple linear regression but when I used the lr.predict function, it shows an error. Here is my code

import pandas as pd
from sklearn.linear_model import LinearRegression as lr

train = pd.read_csv('/content/Project.csv')
test = pd.read_csv('/content/Project Test.csv')

x = train(("Pengalaman kerja", "Banyak Projek (Pemeran Utama)", "Banyak Projek (Pemeran Pendukung)"))
y = train("Banyak Tawaran Project")

xtest = train(("Pengalaman kerja", "Banyak Projek (Pemeran Utama)", "Banyak Projek (Pemeran Pendukung)"))

x_test = test.iloc(:,(1,2,3))

fitprediction = lr.predict(x_test)

The last line is where it shows an error
TypeError Traceback (most recent call last)
in ()
—-> 1 fitprediction = lr.predict(x_test)

TypeError: predict() missing 1 required positional argument: ‘X’
