I need to read a large file, line by line. Lets say that file has more than 5GB and I need to read each line, but obviously I do not want to use readlines()

Thank you! I have recently converted to python 3 and have been frustrated by using readlines(0) to read large files. This solved the problem. But to get each line, I had to do a couple extra steps. Each line was preceded by a "b'" which I guess that it was in binary format. Using "decode(utf-8)" changed it ascii.
Then I had to remove a "=\n" in the middle of each line.
Then I split the lines at the new line.
b_data=(fh.read(ele[1]))#endat This is one chunk of ascii data in binary format
a_data=((binascii.b2a_qp(b_data)).decode('utf-8')) #Data chunk in 'split' ascii format
data_chunk = (a_data.replace('=\n','').strip()) #Splitting characters removed
data_list = data_chunk.split('\n') #List containing lines in chunk
#print(data_list,'\n')
#time.sleep(1)
for j in range(len(data_list)): #iterate through data_list to get each item
i += 1
line_of_data = data_list[j]
print(line_of_data)
Here is the code starting just above "print data" in Arohi's code.
