Python: How do I save a graphic?

b="pic.png"
hpprime.eval('AFiles(" '+b+' "):=G1')

It's important to use the single and double quotes as shown.

There is another solution, and it seems even better to me because MicroPython on HP Prime supports %-formatting of strings, which can be used here.

Code:

b="pic.png"
hpprime.eval('AFiles("%s"):=G0' %b)

It works And as you can see, there is no use of string concatenation.

You can also create a string containing several placeholders marked with '%', and then specify all the variables you want to substitute into those places one by one:

Code:

a="number"
b=12345
s='My text - label %s: %d' %(a,b) 
print(s)

and it prints:
My text - label number: 12345

Here '%s' is used to embed strings, '%d' for integers and '%f' for floating-point values.
