Answer 2

Yes, the += operator is overloaded to include adding strings together.
Since you strings, h, e, l, l, and o, are just one character each; your code should look like this:
x = ""
x += "h"
x += "e"
x += "l"
x += "l"
x += "o"
print x

Answer 6

As far as I know strings are immutable in Python, but you can do things like this:


x="hello"
print x
x=x[:4]+' n'+x[4:] #this being what I think you want
print x
