python2和python3的不同点_Django python2和python3的区别

查看django源码six.py,发现Django在python2和python3的区别：if PY3:

string_types = str,

integer_types = int,

class_types = type,

text_type = str

binary_type = bytes

MAXSIZE = sys.maxsize

else:

string_types = basestring,

integer_types = (int, long)

class_types = (type, types.ClassType)

text_type = unicode

binary_type = str

# 判断是不是Jython

if sys.platform.startswith("java"):

# Jython always uses 32 bits.

MAXSIZE = int((1 << 31) - 1)

else:

# It's possible to have sizeof(long) != sizeof(Py_ssize_t).

class X(object):

def __len__(self):

return 1 << 31

try:

len(X())

except OverflowError:

# 32-bit

MAXSIZE = int((1 << 31) - 1)

else:

# 64-bit

MAXSIZE = int((1 << 63) - 1)

del X

从代码可以看出Django在py2和py3区别还是挺明显
