SyntaxError

[DaveG]

Hi

Could someone identify the reason for my syntax error in the python2 script please?

Error:
  File "init_collapse.py", line 223
    print(("%d %d %d") % (shape(kxx)[1], shape(kxx)[0], collapse_steps), file=f)
                                                                                                                       ^   
SyntaxError: invalid syntax

Probably the line above it, or it could be an indenting error. Nothing wrong with the statement itself.

That is a particularly awkward looking statement. I really dislike that old style of formatting. If you are using Python 3.6 or newer you could write it like this:

print(f"{shape(kxx)[1]} {shape(kxx)[0]} {collapse_steps}", file=f)

You gotta move up from 2.7.

Thank you. I'm just trying to get a script written by someone now deceased to work, I have no real python scripting skills. This is the line above, is the syntax error in this?

f=open(file_ls,"w")
	print(("%d %d %d")%(shape(kxx)[1],shape(kxx)[0],collapse_steps),file=f)

Many thanks.

Should be this:

f=open(file_ls,"w")
print(("%d %d %d")%(shape(kxx)[1],shape(kxx)[0],collapse_steps),file=f)

Python 2.whatever might be more forgiving about indentation, and the error might even be before this.

Are you changing Python versions? You say this is a Python 2 script. Are you using Python 2 or Python 3?
