Review of Phython

Question

Rewrite the following code in python after removing all syntax error(s). Underline each correction done in the code.

STRING=''WELCOME
NOTE''
for S in range[0,8]:
print STRING(S)
print S+STRING

Answer

STRING= 'WELCOME'
NOTE=''
for S in range (0,8):
print STRING [S]
print S, STRING
Also, range(0,8) will give a runtime error as the index is out of range. It should be range(0,7)
