Drop a row if it contains a certain value in pandas

[deltanov]

I have this text file:

LEU,LEID,PPP,YYY,LEO
'1','2','3','4','5'
'2','1','2','3','4'
'2','AA','','',''

I want to delete the rows where for LEID='1'

I wrote this code:

import pandas as pd

#import numpy
import os

originalFile=os.path.abspath("D:\\python\\test\\OriginalFile.csv")
df = pd.read_csv(originalFile)
#df.drop(df.LEID == '1')


df=df[df.LEID != '1']

df.to_csv('D:\\python\\test\\CorrectedFile.csv')
print (df)

Why the row with LEID='1' is not delted?
