Pyfun

Pyfun is a programming language in which only the following five characters are allowed
 a [ ] + <
Pyfun is designed such that it can be easily converted into python 3. 
To convert pyfun code to python code,
you have to replace the word code in the following python code with your pyfun code.
 import sys
 a=[0]
 while True:
 a=code
 if a[0]==1:
 a[1]=ord(sys.stdin.read(1))
 if a[0]==2:
 sys.stdout.write(chr(a[1]))
 sys.stdout.flush()
 if a[0]==3:
 break
For example, if the pyfun code is
 [+[[]<][[]<[]]+[[]<][[]<[]]+[[]<][[]<[]]]
Then, the python code would be
 import sys
 a=[0]
 while True:
 a=[+[[]<][[]<[]]+[[]<][[]<[]]+[[]<][[]<[]]]
 if a[0]==1:
 a[1]=ord(sys.stdin.read(1))
 if a[0]==2:
 sys.stdout.write(chr(a[1]))
 sys.stdout.flush()
 if a[0]==3:
 break
