Wtf when I run this code it gives me an error of indented block...i tried it several time but in vein. What is indented?

Question

i = 2

while i <=6:
print (i)
i=i+1
print("Finished!")

Answer 1

Indenting means adding blank spaces at the beginning of a Python line. Roughly speaking, an indented line doesn't begin at column 1, but at col 3 or 5 or 7... This way is how blocks are identified in Python.
Take a look at your code: which sentence(s) are to be included inside the while loop? The print(i)? Also the i=i+1? The final print as well?
Depending on the answers, you should indent the corresponding lines.

[EDIT:] For example:
for x in range(20):
print(x) # this line is indented
print("Finished") # this line is NOT

Answer 2

Python need ident the code:

try this:

while i<=6
print (i)
i = i + 1
print ("Finished")
