Using pylint to display Error and Warnings simultaneously - python-2.7

Question

I am trying to use pylint to display warning and errors ,
i want all warnings and error to be displayed at the same time , i.e
when i do:
pylint pylint_1.py -rn -d=R,C
it should siplay me all warning and errors ,
but instead what happens is when my program has some errors (indentation error)
it will only show the erros , warning are suppressed .
also if program has indenation errors at two places it will show only the first error .
Here is my sample file :
import string
def somefun():
shift = 3
choice = raw_input("would you like to encode or decode?")
word = (raw_input("Please enter text"))
count_un = 10
letters = string.ascii_letters + string.punctuation + string.digits
encoded = ''
if choice == "encode":
for letter in word:
if letter == ' ':
encoded = encoded + ' '
else:
x = letters.index(letter) + shift
encoded=encoded + letters[x]
if choice == "decode":
for letter in word:
if letter == ' ':
encoded = encoded + ' '
else:
x = letters.index(letter) - shift
encoded = encoded + letters[x]
print encoded
output :
When only warning is their :
No config file found, using default configuration
************* Module pylint_1
W: 6, 4: Unused variable 'count_un' (unused-variable)
When i do a indentation error:
No config file found, using default configu
************* Module pylint_1
E: 22, 0: unexpected indent (syntax-error)
Clearly ,it's visible warning is suppressed when error is there
I am new to pylint , please let me know if my effort is correct ,
i.e what i am trying is possible or not .
Is it possible to display all the warnings and errors in one go .??
