If -Else condition in Pandas to create CSV in separate folders

I am new to python and trying to apply if-else condition over a dataframe.

If the ACCOUNT_LOGIN contains any special character create the csv under a ErrorFolder. else create the csv under ValidatedDataFolder

But the below is also creating a file under ValidatedDataFolder alongwith ErrorFolder even . How to acheive this validation of creating csv in different folders based on if-else condition?

dataframe ACCOUNT_LOGIN : [ AL&L@WA, ANGLIND, ASIGAFU ]

def validate(rowsofdataframe):

filename="TestFileSpclCharOp.txt" 

if  rowsofdataframe['ACCOUNT_LOGIN_1'].strip().isalnum()==False : #if any row contains any spcl character
    output_error_file=os.path.join(errorPath,filename)
    rowsofdataframe.to_csv(output_error_file,index=False)
    val="Login contains special character.FAILED"
else :
   
    validated_Files=os.path.join(foramttedPath,filename)
    rowsofdataframe.to_csv(validated_Files,index=False)
    val="All validation passed" 
    
return val

dfwithcolumns['Status'] = dfwithcolumns.apply(validate, axis=1)
