if conditions in the for indentation doesnt work ?

[Sutsro]

Hello Everyone,

I am trying to get the lines that contain test string or if its not found i want to print not found message. However this doesnt seem to work i dont get any messages at all.

I can read text file, i can even make it count with "for line in input:" however none of the if conditions work inside for indentation. Am i missing something ?

def verial():
  
    isimsatırlistesi=list()
    satırsayısı=0
    input = text1.get("1.0",'end-1c')
    for line in input:
        satırsayısı=satırsayısı+1
        if "test" in line:
            isimsatırlistesi.append(int(satırsayısı))
            print(isimsatırlistesi[0,"end"])
            if len.isimsatırlistesi<0:
                print("test not found")
