split string based on special characters python

Question

I have a string as such:

teststring = 'Index: WriteVTKOutput.FOR\\r\\n======================================\\r\\n'

I'd like to split it based on the '\\\\r' and '\\\\n' characters, such that I get the following result:

testlist = ['Index: WriteVTKOutput.FOR', '======================================']

I tried the following commands, none of which worked:

teststring.split(r'\r\n')
teststring.splitlines()

How does a man split that string into those delimiters while retaining his dignity and keeping it real?

Thanks

Answer 1

这应该做的工作：

lst = teststring.split("\\r\\n")[:-1]

Answer 2

splitlines won't work because your separators aren't really line separators. They're just the actual \\r\\n chars.

You can get rid of trailing/leading empty fields that split generates by an extra comprehension in case your string starts or ends by r"\\r\\n" :

[x for x in teststring.split(r'\r\n') if x]

result:

['Index: WriteVTKOutput.FOR', '======================================']

Answer 3

teststring = 'Index: WriteVTKOutput.FOR\\r\\n======================================\\r\\n'
print(teststring.split("\\r\\n")[:-1])
print(teststring.strip("\\r\\n").split("\\r\\n"))

Output

['Index: WriteVTKOutput.FOR', '======================================']
['Index: WriteVTKOutput.FOR', '======================================']

Answer 4

You need : '\\\\r\\\\n' or r'\\r\\n'

teststring = 'Index: WriteVTKOutput.FOR\\r\\n======================================\\r\\n'
new_string = [x for x in teststring.split('\\r\\n') if x]
