  Here, first we are assigning "Config1" to a, then printing it.

  Output of print(a) would be "Config1".

  Then we are initializing the value of b equal to a, i.e "Config1", thus b will be having value "Config1". Now, a += "config2" appends "config2" to the value of a i.e "Config1", therefore the value of a becomes "Config1config2", b is still having the value "Config1".

  On printing, the value of a would be "Config1config2" and value of b would be "Config1".
