Ah, I was confused then.  Sorry: I just saw the word "Debian" and that
activated my Unix reptile brain.

Sorry for the late reply, but it sounds like it could help a few people here...

The feature you're looking for is called "QuickEdit Mode". There is a
checkbox in the Options tab of the cmd.exe properties dialog. While
you're at it, I recommend configuring the cursor size and optionally
the command buffer size. Then switch tabs and see if you can configure
a better font. Then switch to the layout tab and hard-code a
full-screen size for the window. Everybody knows the stupid cmd.exe
window cannot be dynamically sized, but you can manually configure the
screen buffer and window size to get something much more friendly.
cmd.exe sucks, but if you take a few minutes to configure it then it
sucks considerably less. Add clink to make it suck a bit less still.

HTH.

[Tutor] Is there a way to use "with" across suite boundaries?

[Jim Mooney Py3.4.3winXP]

'''I was using with open...:, but I'm printing a header in one function,
calling a looping
function to print detail lines, then returning to the calling function to
print
the footer. But that didn't work since the with statement only seems to work
with the lexical suite and the file wasn't open in the detail print
function. Is there
a way around this, other than passing the file as I have here? Also, is it a
good idea to pass a file handle like that or is there a better way?

Using the below csv file  co2-sample.csv  to print a simple HTML table
(header omitted)
Since this is a file there are enclosing single quotes not visible:

"ANTIGUA AND BARBUDA",0,0,0,0,0
"ARGENTINA",37,35,33,36,39
"BAHAMAS, THE",1,1,1,1,1
"BAHRAIN",5,6,6,6,6
"SPANISH INQUISITION, THE, SILLY",10,33,14,2,8

Program follows (py3.4, winxp):'''

htbegin = '''


htest

table, td {border:2px solid black; border-collapse:collapse;}
td {padding:3px; background-color:pink;
text-align:right;font-family:verdana;}
td.l {text-align:left}





'''

htend = '''



'''

def make_lines():
co2 = open('co2-sample.csv')
ht = open('output.html', 'w')
linelist = []
print(htbegin, file=ht)
for line in co2:
newlist = line.rsplit(',', 5) # ending is regular so split it out
first
for token in newlist: # since split char inside quotes for
nation is problematic
linelist.append(token.strip('"')) # get rid of extra quotes
linelist[-1] = linelist[-1].strip()
fprint(linelist, ht)
linelist = []
co2.close()
print(htend, file=ht)
ht.close()


def fprint(linelist, ht):
# size formatting irrelevant for HTML
formatted_string = "{}{}{}{}{}{}".format(*linelist)
print(formatted_string, file=ht)
print('', file=ht)


if __name__ == "__main__":
make_lines()

Something else must have gone wrong as

def make_lines():
with open('co2-sample.csv') as co2:
with open('output.html', 'w') as ht:
linelist = []
print(htbegin, file=ht)
for line in co2:
newlist = line.rsplit(',', 5)
for token in newlist:
linelist.append(token.strip('"'))
linelist[-1] = linelist[-1].strip()
fprint(linelist, ht)
linelist = []
print(htend, file=ht)

should run without error. Also possible:

with open('co2-sample.csv') as co2, open('output.html', 'w') as ht:
...

But may I suggest that you delegate parsing the CSV to the standard library? 
Then you can write

import csv

def make_lines():
with open('co2-sample.csv') as co2:
rows = csv.reader(co2)
with open('output.html', 'w') as ht:
print(htbegin, file=ht)
for linelist in rows:
fprint(linelist, ht)
print(htend, file=ht)
