Array of tuples to DataFrame

How can I convert an array of tuples (NOT named tuples) into a DataFrame?
Code to create an array of named tuples:

parking_sections = []

for i in 1:10
   push!(parking_sections, (i, rand(1)[1]))
end

So easy:

using DataFrames

parking_sections = []

for i in 1:10
   push!(parking_sections, (i, rand(1)[1]))
end
DataFrame(parking_sections, [:a, :b])
