No need to use str.replace or string.replace here, just convert that string to a raw string:

>>> strs = r”C:UsersJoshDesktop20130216″

^

|

notice the ‘r’

Below is the repr version of the above string, that’s why you’re seeing here. But, in fact the actual string contains just ” not .

>>> strs

‘C:UsersJoshDesktop20130216’

>>> s = r”fo”

>>> s #repr representation

‘fo’

>>> len(s) #length is 3, as there’s only one `”`

3

But when you’re going to print this string you’ll not get ‘’ in the output.

>>> print strs

C:UsersJoshDesktop20130216

If you want the string to

show ‘’ during print then use str.replace:

>>> new_strs = strs.replace(‘’,’\’)

>>> print new_strs

C:UsersJoshDesktop20130216

repr version will now show \:

>>> new_strs

‘C:\Users\Josh\Desktop\20130216’

The double slash (//) operator is used in python for different purposes. One use of this operator is to get the division result. The division result of two numbers can be an integer or a floating-point number. In python version 3+, both the single slash (/) operator and the double slash (//) operator are used to get the division result containing the floating-point value.

One difference is that the single slash operator returns proper output for the floating-point result, but the double slash operator can’t return the fractional part of the floating-point result. Another use of the double slash (//) operator is to internally define the window path value. Two uses of the double slash (//) operator have been shown in this tutorial.

Example-1: Division using single slash (/) and double slash

(//) operator

Create a python file with the following script to check the difference between the output of the single slash and double slash operator for the division operation. In the script, 5 is defined as the divider value, and 2 is defined as the divisor value. The division result and the type of the result of 5/2, 5//2, 5//2.0, and 5.0//2 will be printed after executing the script.

# Define the divider value

num1 = 5

#

Define the divisor value

num2 = 2

# Divide using single slash

result = num1 / num2

print(“The division result of %d/%d = %0.2f” % (num1, num2, result))

print(“The type of the result”,

type(result))

# Divide using double slash

result = num1 // num2

print(“The division result of %d//%d = %0.2f” % (num1, num2, result))

print(“The type of the result”, type(result))

# Divide using double slash and float divisor

value

result = num1 // float(num2)

print(“The division result of %d//%0.2f = %0.2f” % (num1, num2, result))

print(“The type of the result”, type(result))

# Divide using double slash and float divider

value

result = float(num1) // num2

print(“The division result of %0.2f//%d = %0.2f” % (num1, num2, result))

print(“The type of the result”, type(result))

Output:

The following output will appear

after executing the script. The result of 5/2 is appropriate, and the return type is float. The result of 5//2 is not appropriate, and the return type is an integer. The fractional part has been omitted from the output. The result of 5//2.00 is not appropriate, and the return type is float. The fractional part has been omitted from this output also. The result of 5.00//2 is not appropriate, and the return type is float. The fractional part has been omitted from this output also.

Example-2: Replace the path defined by the double slash (//) operator

The backward slash () is used to define the path in windows, and slash (/) is used to define the path in Linux operating system. When any windows path is

defined in a python variable, then the backward slash () is stored by the double slash (). So, the double slash () requires to convert into forward-slash (/) to define the path in Linux format. Create a python file with the following script that assigns a windows path into a variable and replaces the double slash of the path with the forward-slash (/). The original and updated paths will be printed after executing the script.

# Define a path

pathVal =

r”C:WindowsSystemSpeech”

# Print the path value

print(“The original path value:n”, pathVal)

# Replace the path by forward slash(/)

updated_path = pathVal.replace(“”, “://boxhoidap/”)

# Print the updated

path

print(“The updated path value:n”, updated_path)

Output:

The following output will appear after executing the script. The output shows that the windows path has been converted into the Linux path format.

Conclusion:

The use of the double slash (//) operator in Python 3+ has been shown in this tutorial by using simple examples to understand

the purposes of using this operator.

How do you do a double backslash in Python?

In Python, you use the double slash // operator

to perform floor division. This // operator divides the first number by the second number and rounds the result down to the nearest integer (or whole number).

How do you print a backslash in Python?

For completeness: A backslash can also be escaped as a hex sequence: “x5c” ; or a short Unicode sequence: “u005c” ; or a long Unicode sequence: “U0000005c” . All of these will produce a string with a single backslash, which

Python will happily report back to you in its canonical representation – ‘’ .

What does the double slash do in Python?

Python has two division operators, a single slash character for classic division and a double-slash for “floor” division (rounds down to nearest whole number). Classic division means that if the operands are both integers, it will perform floor division, while for floating point numbers, it represents true

division.

How do you change a double backslash to a single backslash in Python?

4 Answers.

This works with the print, but not without it. print s.replace(‘\’, ‘’) => some doubles . … .

string.replace() returns the object, you would have to to s = s.replace() – Inbar Rose. … .

Sorry, this doesn’t work. … .

@mill Wouldn’t you still need the backslash to be

escaped in the actual string/variable? :).
