Getting rid of Carriage return and new line in a string

I have a string of the form 

b'helloworld\r\n'

I would like to strip it of the \r\n and the the starting b. I tried using .rstrip("\n") but it crashes the system.

you can also decode the b-string (bytes-string), using .decode() and then print() it:

>>> yourBytesString = b'helloWorld\r\nnextLine\n'
>>> print(yourBytesString)
b'helloWorld\r\nnextLine\n'
>>> yourBytesString.decode()
'helloWorld\r\nnextLine\n'
>>> print(yourBytesString.decode())
helloWorld
nextLine

According to the Python docs, the b prefix means that your string is a byte string. Specifically:

A prefix of 'b' or 'B' is ignored in Python 2; it indicates that the literal should become a bytes literal in Python 3 (e.g. when code is automatically converted with 2to3). A 'u' or 'b' prefix may be followed by an 'r' prefix.

To convert this to a string without trailing newline and return, and to remove the byte prefix, you would use:

str(b'helloworld\r\n').rstrip('\r\n')

Try this:

b'helloworld\r\n'.strip() // leading + trailing

or

b'helloworld\r\n'.rstrip() // trailing only

There shouldn't be any problem. Just do:

your_string.rstrip()

rstrip() without any parameters strips whitespaces, newlines and carriage returns.

Examples:

>>> s = 'helloworld\r\n'
>>> print s.rstrip()
helloworld


>>> s = 'helloworld             \r\n'
>>> print s.rstrip()
helloworld
