Does Python do variable interpolation similar to “string #{var}” in Ruby?

Question

In Python, it is tedious to write:

print \"foo is\" + bar + \'.\'

Can I do something like this in Python?

print \"foo is #{ba

Answer 1

Python 3.6 has introduced f-strings:

print(f"foo is {bar}.")

Old answer:

Since version 3.2 Python has str.format_map which together with locals() or globals() allows you to do fast:

Python 3.3.2+ (default, Feb 28 2014, 00:52:16) 
>>> bar = "something"
>>> print("foo is {bar}".format_map(locals()))
foo is something
>>> 

Answer 2

Yes, absolutely. Python, in my opinion, has great support for string formatting, replacements and operators.

Answer 3

String formatting

>>> bar = 1
>>> print "foo is {}.".format(bar)
foo is 1.
