Question

Suppose we have a string a = "01000111000011" with n=5 "1"s. The ith "1", I would like to replace with the ith character in "ORANGE".
My result should look like:

b = "0O000RAN0000GE"

What could be the finest way to solve this problem in Python? Is it possible to bind an index to each substitution?

Many thanks!

Tons of answers/ways to do it. Mine uses a fundamental assumption that your #of 1s is equal to the length of the word you are subsituting.

a = "01000111000011"
a = a.replace("1", "%s")
b = "ORANGE"
print a % tuple(b)

Or the pythonic 1 liner 😉

print "01000111000011".replace("1", "%s") % tuple("ORANGE")
