Method 1: Use textual content studying mode when opening information.

Simply put, python 2 will settle for information in binary, nevertheless python 3 solely accepts information in textual content. So the fast approach to deal with the error is to change the file opening mode by altering wb to w, like under:

Before: outfile=open('./immates.csv','wb')

After: outfile=open('./immates.csv','w')

Method 2: Convert all to binary

<font fashion="vertical-align: inherit;"><font fashion="vertical-align: inherit;">if b'captain America 'in singleLine:</font></font>

Thus, all information has agreed on one kind, error is dealt with.

Method 3: Using decode() or Encode() perform

With the method from decode(), you’ll decode the traces in this system in order that python can learn it. Examples are as follows:

# Import gzip module
import gzip
# initialize line_count variable 
# Open file with gzip module
with'myfile.sql.gz', 'rb') as fin:
        for line in fin:
            if (total_lines == 0):
                number_columns = line.decode('utf8').strip('n').cut up('t')
                print('Print File Rows: ',number_columns);

Besides, you can too resolve the error with encode(). The perform encodes an object to the desired object, in this case a Byte object. For instance:

with open('file.txt', 'rb') as f:
    traces = [x.strip() for x in f.readlines()]
for line in traces:
    tmp = line.strip()
    split_line = tmp.cut up('-'.encode())
    if 'Samsung Galaxy S21 ' in str(split_line[0]):
        print("Price = ", split_line[1])
