Why am I getting a SyntaxError when using `end=' '` with `print` in Python?

Querying SyntaxError on print with end=' '

When attempting to utilize the code:

if Verbose:
   print("Building internam Index for %d tile(s) ...", end=' ')

you are met with a SyntaxError indicating that end=' ' is incorrect syntax. This error stems from a crucial distinction between Python 2.x and 3.x.

In Python 2.x, print is regarded as a statement rather than a function. Consequently, using keyword arguments like end is not permissible. Instead, you must separate arguments with commas or utilize a tuple as an argument to the print statement. For example, in Python 2.x, the code above is equivalent to:

print(("Building internam Index for %d tile(s) ...", end=" "))

or

print("Building internam Index for %d tile(s) ...", end=" ")

However, in Python 3.x, print is a bona fide function and accepts keyword arguments. This allows for a more streamlined syntax, where you can specify keyword arguments directly to the print function, as in the original example.

To resolve this issue in Python 2.x, you can modify the code to separate arguments with commas or employ the sys.stdout module for more comprehensive control over output. Alternatively, in recent versions of Python 2.x (2.5 and above), you can import the future module and enable the print_function feature:

from __future__ import print_function

This will enable the enhanced print function syntax in your script file, allowing you to utilize keyword arguments like end. Note that this approach is not universally compatible with older versions of Python 2.x.
