I want to run some python code i.e. example.py.
I don't want to enter code manually into Python shell since it slow:
x = 1
x
y = 2
y + x
y
And I'd like to achieve such output:
>>> x = 1
>>> x
1
>>> y = 2
>>> y + x
3
>>> y
2
It looks that is simple to answer, but very hard to find how to do it.
Since there was some questions this is not pattern to document "large code" that is for documenting/testing code snippets/examples!
You can do that with the InteractiveConsole in the code module, and it support multilines:
import code
console = code.InteractiveConsole()
more_input = False
with open('example.py') as source:
for line in source:
if not more_input:
print('>>> ' + line.rstrip())
else:
print('... ' + line.rstrip())
more_input = console.push(line)
If you wonder how the more_input flag works, take a look at the doc:
InteractiveConsole.push(line):[...] The return value is True if more input is required, False if the line was dealt with in some way (this is the same as
runsource()).
I've test it on an example.py that looks like:
x = 1
x
y = 2
y + x
a = (
1,
2,
3
)
print(a)
and the result was:
>>> x = 1
>>> x
1
>>> y = 2
>>> y + x
3
>>>
>>> a = (
... 1,
... 2,
... 3
... )
>>> print(a)
(1, 2, 3)
You could try something like this:
f = open('example.py', 'r')
for line in f:
print('>>> ' + line)
try:
print(eval(line))
except SyntaxError:
exec(line)
global _; _= eval(line); if _ is not None: print( _ ) to get slightly closer to REPL behavior.
>>> ... lines.I would not know a way to do so. But you don't have to enter it manually - just do copy & paste...
