The following python snippet does execute normally from a Python (2.7)
temporary buffer
Source : =========================================
print "Start of block called from a Python temporary buffer"
print NomDeFichier
try:
FN=NomDeFichier
except:
FN="Chose.txt"
finally:
print FN
print "**"+FN+"**"
print "End of block called from a Python temporary buffer"
=========================================
Execution result: =========================================
>>> Start of block called from a Python temporary buffer
Bidule.txt
Bidule.txt
**Bidule.txt**
End of block called from a Python temporary buffer
>>> Start of block called from a Python temporary buffer
Bidule.txt
Bidule.txt
**Bidule.txt**
End of block called from a Python temporary buffer
=========================================
But the following Babel Python block, from which the previous snippet
derives, fails to run :
Block : =========================================
#+begin_src python :var NomDeFichier="Bidule.txt" :exports both
:results file :preamble "# -*- coding: utf-8 -*-"
print "Start of block called from an Org Python block"
print NomDeFichier
try:
FN=NomDeFichier
except:
FN="Chose.txt"
finally:
print FN
# Irrelevant for now:
# F1=file(FN,"w")
# F1.write("Tagada\n")
# F1.write("tsoin-tsoin...\n")
# F1.close()
print "End of block called from an Org Python block"
# Kept to pacify Org...
FN
#+end_src
=========================================
Execution result : =========================================
>>> print "Start of block called from an Org Python block"
Start of block called from an Org Python block
>>> print NomDeFichier
Bidule.txt
>>> try:
... FN=NomDeFichier

=========================================
Possibly relevant : from (packages-list-packages) :
python-mode 20181223.1933 installed Python major
mode
Also posibly relevant : a very similar Sage block, whose edit mode is
sage-shell-mode, runs without problem.
I'm lost. Suggestions ?
