Python Practice Example 43
Python 100 ExamplesProblem:Another case of imitating static variables (static).
Program analysis:Demonstrate a Python scope usage method.
Program source code:
Example
#!/usr/bin/python
# -*- coding: UTF-8 -*-
class Num:
nNum = 1
def inc(self):
self.nNum += 1
print ('nNum = %d' % self.nNum)
if __name__ == '__main__':
nNum = 2
inst = Num()
for i in range(3):
nNum += 1
print ('The num = %d' % nNum)
inst.inc()
# -*- coding: UTF-8 -*-
class Num:
nNum = 1
def inc(self):
self.nNum += 1
print ('nNum = %d' % self.nNum)
if __name__ == '__main__':
nNum = 2
inst = Num()
for i in range(3):
nNum += 1
print ('The num = %d' % nNum)
inst.inc()
The output result of the above example is:
The num = 3 nNum = 2 The num = 4 nNum = 3 The num = 5 nNum = 4Other extensions
