In connection with another post by Andreas, I realised that the above
ashow() definition does not create nice output if decimal numbers are
involved:
y = 0.5*x
ashow('y')
returns:
y=0.500x
Is there a way of manipulating the eval() command to round a decimal
number? If so, I would be
This does not format things like a_2 very well. What about this one?
def ashow(v):
show(sage.calculus.calculus.var(v)==eval(v))
Show seems to format the equations nicely without explicitly using
latex.
If latex is desired explicitly, the following works, too:
def ashow(v):

Thank you all for your replies! I was overwhelmed by your fast and
helpful replies!
I may should have described my desired result in more detail:
I don't wanna display/print out the line
a = \frac{{2 q}}{3}
but I would like to Sage display it, as if it was processed by latex
(the look of a
Or is there a way to access the content of a variable, when you only
have a string with its name?
'Eval' can do that :
def ashow(v):
show($+v+=%s$%latex(eval(v)))
b=2/3
ashow('b')
Hope that helps

Thank you! That's it.

Or, if you don't like constantly having to repeat the variable name,
something like:
sage: def vshow(_v):
: print '%s = %s\n' % (_v,latex(globals()[_v]))
:
sage: var('q')
q
sage: a = 3*q/2
sage: vshow('a')
a = \frac{{3 q}}{2}
This is far from an ideal solution, as if you call it
Hi samuel,
may you write yourself a wrapper which similar to this:
def ashow(**args):
... for key in args:
... print key,'=',args[key]
...
c = 345.45
ashow(c=c)
c = 345.45
instead of print key,'=',args[key]
one could write
return str(key) + '=' + str(args[key])
the following

hi,
I use sage (in notebook mode) for basic calculations on a daily basis.
I also like to print out my calculations and hand it in with my
exercise.
Since the people who correct them here at the ETH university in Zürich
are not familiar with sage, I would like to
