TypeError: a bytes-like object is required, not 'str' when writing to a file in Python3

Question

I\'ve very recently migrated to Py 3.5. This code was working properly in Python 2.7:

with open(fname, \'rb\') as f:
    lines = [x.strip() for x in f.readli         


        

Answer 1

You have to change from wb to w:

def __init__(self):
    self.myCsv = csv.writer(open('Item.csv', 'wb')) 
    self.myCsv.writerow(['title', 'link'])

to

def __init__(self):
    self.myCsv = csv.writer(open('Item.csv', 'w'))
    self.myCsv.writerow(['title', 'link'])

After changing this, the error disappears, but you can't write to the file (in my case). So after all, I don't have an answer?

Changing to 'rb' brings me the other error: io.UnsupportedOperation: write
