问题
Considering the following interactive shell session.
Python 2.7.5+ (default, Feb 27 2014, 19:37:08)
[GCC 4.8.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 1+1
2
>>> 2+5
7
>>> "foo"
'foo'
>>>
Observe how, after every line, the interpreter will echo the result to the console.
If I put those same three commands into a script Foo.py without print statements, there will be no output generated.
Is there a way to force the Python interpreter to generate the same output as it would under interactive mode without modifying the code to manually insert print statements?
回答1:
import code
console = code.InteractiveConsole()
prompt = '>>>'
source = '''
1 + 1
2+5
"foo"
x = 1
x
y = (2+
3)
y + x
'''.splitlines()
for line in source:
print('{p} {l}'.format(p=prompt, l=line.rstrip()))
prompt = '...' if console.push(line) else '>>>'
yields
>>>
>>> 1 + 1
2
>>> 2+5
7
>>> "foo"
'foo'
>>> x = 1
>>> x
1
>>> y = (2+
... 3)
>>> y + x
