python - TypeError: expected a character buffer object

Question

I am running into the following error while writing the value into a file. Can you please help me figure out what is the issue here and how to fix it?

row = 649
with open(r'\locdevBuild_veruild_ver.txt','r+') as f:
    f.write(row)
print row

Error:

Traceback (most recent call last):
  File "latest_rev.py", line 6, in <module>
    f.write(row)
TypeError: expected a character buffer object

Answer 1

Assuming you just want to write the string '649' to the file, change row to '649' or issue f.write(str(row)).
