Python Exercise Example 42
Python 100 ExamplesProblem:Learn to use the auto keyword to define variables.
Program analysis:There is no auto keyword; use variable scope as an example.
Program source code:
Example
#!/usr/bin/python
# -*- coding: UTF-8 -*-
num = 2
def autofunc():
num = 1
print ('internal block num = %d' % num)
num += 1
for i in range(3):
print ('The num = %d' % num)
num += 1
autofunc()
# -*- coding: UTF-8 -*-
num = 2
def autofunc():
num = 1
print ('internal block num = %d' % num)
num += 1
for i in range(3):
print ('The num = %d' % num)
num += 1
autofunc()
The output of the above example is:
The num = 2 internal block num = 1 The num = 3 internal block num = 1 The num = 4 internal block num = 1Other extensions
