How to loop through a dictionary in Julia?

Question

I want to loop through and print the (key, value) pairs of a dictionary in Julia. How can I do this?

I see how to initalize a dictionary in Julia here, but I want to loop through it as well.

Answer 1

The solution is relatively simple:

x = Dict("a"=>"A", "b"=>"B", "c"=>"C")

for (key, value) in x
    print(key); print(value)
end

# Output: cCbBaA

Check out the Julia docs for Base.Dict to learn more about functions you can apply to a Dictionary in Julia!

Answer 2

you can also use this solution:

x = Dict("a"=>"A", "b"=>"B", "c"=>"C")

for item in x
    print(item.first)
    print(" : ")
    println(item.second)
end

# output: 
#   c : C
#   b : B
#   a : A
