- The code has some issues and may have bugs. Use it at your own risk.
- Raising StopIteration in Python <= 3.6 will halt or close generator but in Python >=3.7, this will raise Runtime Error
- Reading ex.txt:
#header
abc
1 2 3
xyz
4 5 6
end
#header
again
11 22 33
end
- We may stop when
endkeyword is found - In generator_py36.py, finding
endwill rais StopIteration and it works OK in Python/3.6 but crashes in 3.7 - generator_py37.py shows how to use close() function for the generator
- A typical while loop for generator in Python 3.6 or older
def action():
while True:
yield do_something()
- In Python 3.7 or higher, StopIteration will raise a runtime error and this might be modified as:
def action():
while True:
try:
yield do_something()
except StopIteration:
