Ask:
PEP8 explicitly specifies 79 characters, however, PyCharm defaults to 120 and gives the warning "PEP8: line too long (...> 120 characters)".
Does previous PEP8 version use 120 and PyCharm doesn't update its PEP8 checker? I can't find any PEP8 guides for previous versions, however, I can easily find PEP8 Python scripts for previous versions.
I'm starting a new Python project and I'm not sure which one to use.

answer:
PyCharm is built on IntelliJ. IntelliJ's default line length is 120 characters.
It's probably because you can't fit a normal Java name, eg: @annotated public static MyObjectFactoryFactory enterpriseObjectFactoryFactoryBuilderPattern {only 80 characters. (I like it, but Java names tend to get longer by convention).
The pep8 checker is configurable, so you can specify a better maximum line length - for example 79 characters.
The error is misleading because the pep8 checker uses a similar format to format the text "PEP8: line too long(... > %s characters)" % max_line_setting. So it uses the pep8 checker, with a specific configuration, instead of claiming that pep8 specifies 120 character lines.

Python code wrapping is adding a \ after each line
Take a chestnut:
time = "2017"
print "one" + "," \
+ "two" \
+ ",three" + \
"," + time
It prints out:
one,two,three,2017
Take another chestnut:
print "this line is toooooooooooo \
long"
print it out:
this line is toooooooooooo long
