Nevermind,my mistake,found the problem and fixed it.

It should be information.build, you should access it the same way as as you access the other ones that are assigned in the same way.

Nevermind,my mistake,found the problem and fixed it.

Some pointer,there are a style issues and none stander way of doing this stuff.
So here we go:
Indentation is always 4 space,object make no sense in Python 3.x,and class should have capital letter.
PEP 396 Module Version Numbers:

3) When a module (or package) includes a version number, the version SHOULD be available in the __version__ attribute.
5) The __version__ attribute's value SHOULD be a string.

Eg:

class Information:
    __version__ = '1.0'

Use it:

>>> Information.__version__
'1.0'
>>> obj = Information()
>>> obj.__version__
'1.0'

str(majorVersion)+'.'+str(minorVersion)

Drop str() and + Python has string formatting.

>>> majorVersion = 1.0
>>> minorVersion = 0.98
>>> print('majorVersion is: {}\nminorVersion is: {}'.format(majorVersion, minorVersion))
majorVersion is: 1.0
minorVersion is: 0.98

In 3.6 there is also f-string.

>>> majorVersion = 1.0
>>> minorVersion = 0.98
>>> print(f'majorVersion is: {majorVersion}\nminorVersion is: {minorVersion}')
majorVersion is: 1.0
minorVersion is: 0.98
