Python - if în while loop

I am studiing the Python Fundamentals and i have some trouble understanding this folowing example:

c = 1 

while c < 5:
    c = c + 1

    if c >= 4:

        print("string")

        print(c)

   else:

        continue

And the output is:

string

4

string

5

Could someone explain to me please, why i have this output?
