What is Ruby equivalent of Python's `s= "hello, %s. Where is %s?" % ("John","Mary")`
Question:
In Python, this idiom for string formatting is quite common
s = "hello, %s. Where is %s?" % ("John","Mary")
What is the equivalent in Ruby?
Answers:
Almost the same way:
"hello, %s. Where is %s?" % ["John","Mary"]
# => "hello, John. Where is Mary?"
Actually almost the same
s = "hello, %s. Where is %s?" % ["John","Mary"]
The easiest way is string interpolation. You can inject little pieces of Ruby code directly into your strings.
name1 = "John"
name2 = "Mary"
"hello, #{name1}. Where is #{name2}?"
You can also do format strings in Ruby.
"hello, %s. Where is %s?" % ["John", "Mary"]
Remember to use square brackets there. Ruby doesn’t have tuples, just arrays, and those use square brackets.
In Ruby > 1.9 you can do this:
s = 'hello, %{name1}. Where is %{name2}?' % { name1: 'John', name2: 'Mary' }
