Many posts that considered there's no difference between wb and w in Unix environments, e.g. Python file IO 'w' vs 'wb' [duplicate]. But mine works the opposite.
The environment is Ubuntu 16.04 and Python 2.7.13. Executing the following code
from __future__ import print_function
log = open("output.txt", "w")
print('{:02d} {} {} {} {} {}'.format(
queryID,
"Q0",
match[0], # filename
rank,
match[1], # score
config.MY_NAME
), file = log)
Got error:
TypeError: write() argument 1 must be unicode, not str
Then I tried to replace with wb, problem solved, no more error
log = open("output.txt", "wb")
Could anyone help explain what's going on here?
