I'm working on a lesson from Udacity and am having some issue trying to find out if the result from this site returns true or false. I get the TypeError with the code below.
from urllib.request import urlopen
#check text for curse words
def check_profanity():
f = urlopen("http://www.wdylike.appspot.com/?q=shit")
output = f.read()
f.close()
print(output)
if "b'true'" in output:
print("There is a profane word in the document")
check_profanity()
The output prints b'true' and I'm not really sure where that 'b' is coming from.

To solve the Python "TypeError: a bytes-like object is required, not 'str'", encode the str to bytes, e.g. my_str. encode('utf-8') . The str. encode method returns an encoded version of the string as a bytes object.
In Python, a string object is a series of characters that make a string. In the same manner, a byte object is a sequence of bits/bytes that represent data. Strings are human-readable while bytes are computer-readable. Data is converted into byte form before it is stored on a computer.
Write Bytes to File in Python Example 1: Open a file in binary write mode and then specify the contents to write in the form of bytes. Next, use the write function to write the byte contents to a binary file.
In python 3 strings are by default unicode. The b in b'true' means that the string is a byte string and not unicode. If you don't want that you can do:
from urllib.request import urlopen
#check text for curse words
def check_profanity():
with urlopen("http://www.wdylike.appspot.com/?q=shit") as f:
output = f.read().decode('utf-8')
if output:
if "true" in output:
print("There is a profane word in the document")
check_profanity()
Using with will close the urlopen connection automatically.
