Python add character to string

Question

I am trying to open a user's text file and replace a string in Python. I have the replacement working, but to open a file I understand that I need to add another backslash after each one in the file path. I am not sure how to do that. I looked at other stack overflow questions, but they were mostly about adding to the beginning or end of the string. Please help! Here's the code so far:

yourfile = input()

with open ("C:\\Users\\Rajrishi\\Documents\\MyJava\\text.txt") as myfile:
    data = myfile.readlines()
    strdata = "".join(data)
    strdata = strdata.replace("a string","a replacement")
    print(strdata)

Be aware that "C:\\text" means "a 7-character string, whose characters are a C followed by a colon, followed by a backslash, followed by text. Whereas "C:\text" means "a 6-character string, whose characters are a C followed by a colon, followed by a tab character, followed by ext. So there's no question of "adding another backslash to the string" -- the string only needs one backslash for each separator, and the issue is how to get a string that contains a backslash. — Steve Jessop

You may find it easier to pass a raw string by prefixing with r like so:

with open (r"C:\Users\Rajrishi\Documents\MyJava\text.txt") as myfile:

This will mean that you don't need to escape slashes

You can actually use forward slashes:

with open("C:/Users/Rajrishi/Documents/MyJava/text.txt") as myfile:
    ...

If your code and your file in the same folder, you can do this :

with open (r"text.txt") as myfile:
    ...

Just write name of the file.
