Ruby string substitution

Question

Don't know what the term is called (substitution?), but in python if you type ``` num1 = 4 num2 = 2 print("Lucky numbers: %d %d" %(num1, num2)) ``` You get "Lucky numbers: 4 2" How do I do this in ruby? Trying to do the above scenario, it works if I have one variable, but if I need to sub in multiple variables the parentheses aren't valid syntax.

Accepted Answer

```
num1 = 4  
num2 = 2  
print "Lucky numbers: %d %d" % [num1, num2]
```
