How do i get rid of rn in python?

I want to get rid `\r\n' characters in my string to do so, I tried this :

s1.translate[dict.fromkeys[map[ord, u"\n\r"]]]
    lists1=[]
    lists1.append[s1]
    print lists1

I received this:

[u'\r\nFoo\r\nBar, FooBar']

How can I get rid of \r\n characters in my string ?

Use str[] and replace[] to remove both u and \r\n:

In [21]: strs = u'\r\nFoo\r\nBar'

In [22]: str[strs].replace["\r\n",""]
Out[22]: 'FooBar'

or just replace[] to get rid of only \r\n:

In [23]: strs.replace["\r\n",""]
Out[23]: u'FooBar'

cleaned = u"".join[[line.strip[] for line in u'\r\nFoo\r\nBar, FooBar'.split["\r\n"]]]

or just use replace[]:

cleaned = u'\r\nFoo\r\nBar, FooBar'.replace["\r\n", ""]

You could do

'this is my string\r\nand here it continues'.replace['\r\n', '']

Problem

You have a very long string or one that include newline escape characters [\n]. You would like to use Python 3 in order to automatically delete those appended newlines added to your string.

In this post, we will outline three methods that you can use to delete newlines from a string. In this post we’ll discuss each technique and post example code that you can use to follow along.

Using rstrip[] method:

The rstrip[] method removes any trailing character at the end of the string. By using this method, we can remove newlines in the provided string value.

Code:

def removelines[value]:
    return value.rstrip[]

mystring = 'This is my string. \n'
print["Actual string:",mystring]
print["After deleting the new line:",removelines[mystring]]

Output:

Actual string: This is my string

After deleting the new line: This is my string.

Using replace[] method:

To remove any of the newlines found between a string, we can use the replace method and get the newline removed.

Code:

def removelines[value]:
    return value.replace['\n','']

mystring = 'This is my string \nThis comes in the next line.'
print["Actual string:",mystring]
print["After deleting the new line:",removelines[mystring]]

Output:

Actual string: This is my string
This comes in the next line.
After deleting the new line: This is my string This comes in the next line.

Using splitlines[] method:

The splitlines[] method helps to convert the lines into a split list. Hence, we can split our string into a list and then join it to form a string value.

Code:

def removelines[value]:
    return ''.join[value.splitlines[]]

mystring = 'This is my string \nThis comes in the next line.'
print["Actual string:",mystring]
print["After deleting the new line:",removelines[mystring]]

Output:

Actual string: This is my string
This comes in the next line.
After deleting the new line: This is my string This comes in the next line.

Removing newlines from a Python list

In a similar fashion you can easily strip newlines off a list of strings.

Let’s assume you have the following list:

orig_lst = ['Python', 'R', 'GO\n', 'Haskell']

We can easily strip the newlines off the list elements with a list comprehension and the rstrip[] function:

new_lst = [x.rstrip[] for x in orig_lst]
print[new_lst]

Here’s is the result:

['Python', 'R', 'GO', 'Haskell']

Alternatively we can obtain the same result by using the replace[] function:

new_lst = [x.replace['\n',''] for x in orig_lst]

We can also replace the newline characters with a space:

new_lst = [x.replace['\n',' '] for x in orig_lst]
