print ('c:\' ) shows folder name

Question

Please see attached code. This seems to only apply on sololearn interpreter. Can not find details in other documentation.
Why does print ('c:\') show current directory name. I know sololearn is based on windows server which explains c is the drive name. What happens behind the scene to produce this?

Answer 1

print("c:\\") use double slash to print c:\ in output

Answer 2

I understand the escape. I do not understand how a string of 'c:\' translate to the directory name. This only seems to occur within the Sololearn interpreter.
