Ruby difference between for and .each
# They are both similar in function, however the for loop will retain a variable.
# FOR Example:
nums = [1,2,3]
for n in nums
puts n
end
=> 1 2 3
# If you ask what is n, n outputs the last assignment from the function.
n => 3
# EACH Example:
nums.each do |i|
puts i
end
=> 1 2 3
# If you ask what is i.
i => NameError (undefined local variable or method `i' for main:Object)diff between / and // in python
