Thank you ZyX !

I give you the following code if it can help for someone else. Execute-selection-in-Python-and-append-master with a third function that returns only output :
python << EOL
import vim, StringIO, string, sys
def PyExecAppend(line1,line2):
r = vim.current.buffer.range(int(line1),int(line2))
redirected = StringIO.StringIO()
sys.stdout = redirected
exec('\n'.join(r[:]) + '\n')
sys.stdout = sys.__stdout__
output = redirected.getvalue().split('\n')
r.append(output[:-1]) # the -1 is to remove the final blank line
redirected.close()

def PyExecReplace(line1,line2):
r = vim.current.buffer.range(int(line1),int(line2))
redirected = StringIO.StringIO()
sys.stdout = redirected
exec('\n'.join(r[:]) + '\n')
sys.stdout = sys.__stdout__
output = redirected.getvalue().split('\n')
r[:] = output[:-1] # the -1 is to remove the final blank line
redirected.close()

def PyExecOut(line1,line2):
r = vim.current.buffer.range(int(line1),int(line2))
redirected = StringIO.StringIO()
sys.stdout = redirected
exec('\n'.join(r[:]) + '\n')
sys.stdout = sys.__stdout__
output = redirected.getvalue().split('\n')
redirected.close()
return output
EOL
command! -range Pyeo python PyExecOut(<f-line1>,<f-line2>)
command! -range Pyer python PyExecReplace(<f-line1>,<f-line2>)
command! -range Pyea python PyExecAppend(<f-line1>,<f-line2>)




Then I have just a last problem, in my main code that build setqflist I have only the last occurence and not all (6 occurences) despite the 'a' option.


for filepath in myDict.keys():
for line in myDict[filepath]:
print filepath + " line " + '{:>5}'.format(str(line[0])) + " : " + line[1]
vim.Function('setqflist')([{'filename': filepath, 'lnum': line[0], 'text': line[1]},'a'])
