Is there no limit to the minimum integer value of Python?

import sys

t1 = sys.maxint
t2 = sys.maxint+1 #Automatically transforms to long if it exceeds the int range

print(t1)
print(t2)
print(type(t1))
print(type(t2))

<type 'int'>
<type 'long'>

import sys

t1 = sys.maxsize
t2 = sys.maxsize+1 #This is also type int

print(t1)
print(t2)
print(type(t1))
print(type(t2))
