How do you write forward slash in python string?

Use a raw string:

>>> foo = r'baz "\"'
>>> foo
'baz "\\"'

Note that although it looks wrong, it's actually right. There is only one backslash in the string foo.

This happens because when you just type foo at the prompt, python displays the result of __repr__() on the string. This leads to the following (notice only one backslash and no quotes around the printed string):

>>> foo = r'baz "\"'
>>> foo
'baz "\\"'
>>> print(foo)
baz "\"

And let's keep going because there's more backslash tricks. If you want to have a backslash at the end of the string and use the method above you'll come across a problem:

>>> foo = r'baz \'
  File "", line 1
    foo = r'baz \'
                 ^  
SyntaxError: EOL while scanning single-quoted string

Raw strings don't work properly when you do that. You have to use a regular string and escape your backslashes:

>>> foo = 'baz \\'
>>> print(foo)
baz \

However, if you're working with Windows file names, you're in for some pain. What you want to do is use forward slashes and the os.path.normpath() function:

myfile = os.path.normpath('c:/folder/subfolder/file.txt')
open(myfile)

This will save a lot of escaping and hair-tearing. This page was handy when going through this a while ago.

Split a string by forward slash in Python #

Use the str.split() method to split a string on the forward slashes, e.g. my_list = my_str.split('/'). The str.split method will split the string on each occurrence of a forward slash and will return a list containing the results.

Copied!

# ✅ split string on each occurrence of forward slash my_str = 'one/two/three/four' my_list = my_str.split('/') print(my_list) # 👉️ ['one', 'two', 'three', 'four'] # ✅ split string on each space or forward slash my_str_2 = 'one two/three four five' my_list_2 = my_str_2.replace('/', ' ').split(' ') print(my_list_2) # 👉️ ['one', 'two', 'three', 'four', 'five']

The str.split() method splits the string into a list of substrings using a delimiter.

The method takes the following 2 parameters:

NameDescription
separator Split the string into substrings on each occurrence of the separator
maxsplit At most maxsplit splits are done (optional)

If the separator is not found in the string, a list containing only 1 element is returned.

Copied!

my_str = 'one' my_list = my_str.split('/') # 👇️ ['one'] print(my_list)

If your string starts with or ends with a forward slash, you would get empty string elements in the list.

Copied!

my_str = '/one/two/three/four/' my_list = my_str.split('/') print(my_list) # 👉️ ['', 'one', 'two', 'three', 'four', '']

You can use the filter() function to remove any empty strings from the list.

Copied!

my_str = '/one/two/three/four/' my_list = list(filter(None, my_str.split('/'))) print(my_list) # 👉️ ['one', 'two', 'three', 'four']

The filter function takes a function and an iterable as arguments and constructs an iterator from the elements of the iterable for which the function returns a truthy value.

If you pass None for the function argument, all falsy elements of the iterable are removed.

All values that are not truthy are considered falsy. The falsy values in Python are:

  • constants defined to be falsy: None and False.
  • 0 (zero) of any numeric type
  • empty sequences and collections: "" (empty string), () (empty tuple), [] (empty list), {} (empty dictionary), set() (empty set), range(0) (empty range).

Note that the filter() function returns a filter object, so we have to use the list() class to convert the filter object to a list.

If you need to split a string on occurrences of a forward slash and another character, replace the forward slash with the other character and split on that character.

Copied!

my_str_2 = 'one two/three four five' my_list_2 = my_str_2.replace('/', ' ').split(' ') print(my_list_2) # 👉️ ['one', 'two', 'three', 'four', 'five']

We replaced all occurrences of a forward slash with a space and split the string on each space.

You could achieve the same result by replacing each occurrence of a space with a forward slash and splitting on each forward slash.

Copied!

my_str_2 = 'one two/three four five' my_list_2 = my_str_2.replace(' ', '/').split('/') print(my_list_2) # 👉️ ['one', 'two', 'three', 'four', 'five']
