Question

I have the following code:

def search():
    os.chdir("C:/Users/Luke/Desktop/MyFiles")
    files = os.listdir(".")
    os.mkdir("C:/Users/Luke/Desktop/FilesWithString")
    string = input("Please enter the website your are looking for (in lower case):")
    for x in files:
        inputFile = open(x, "r")
        try:
            content = inputFile.read().lower
        except UnicodeDecodeError:
            continue
        inputFile.close()
        if string in content:
            shutil.copy(x, "C:/Users/Luke/Desktop/FilesWithString")

which always gives this error:

line 80, in search
    if string in content:
TypeError: argument of type 'builtin_function_or_method' is not iterable

can someone shed some light on why.

Answer 1

Change the line

content = inputFile.read().lower

to

content = inputFile.read().lower()

Your original line assigns the built-in function lower to your variable content instead of calling the function str.lower and assigning the return value which is definitely not iterable.
