Python将前进（/）替换为前进（/）

Question

I am trying to replace \\ with / . However, I'm having no success. Following is the snapshot of the scenario that I am trying to achieve

string = "//SQL-SERVER/Lacie/City of X/Linservo\171002"        
print string.replace("\\","/")  

Output:

//SQL-SERVER/Lacie/City of X/Linservoy002  

Desired output:

//SQL-SERVER/Lacie/City of X/Linservo/171002

Answer 1

You need to escape "\\" with an extra "\\".

>>> string = "//SQL-SERVER/Lacie/City of X/Linservo\\171002"
>>> string
'//SQL-SERVER/Lacie/City of X/Linservo\\171002'  
>>> print string.replace("\\","/")
//SQL-SERVER/Lacie/City of X/Linservo/171002

Answer 2

string = r"//SQL-SERVER/Lacie/City of X/Linservo\171002"
print string.replace("\\","/")

output

//SQL-SERVER/Lacie/City of X/Linservo/171002

Answer 3

You have errors both in replace function and in string definition.

• In your string definition \\171 gives char with octal value of 171 – y
• In you replace function, backslash escapes quote.

You should escape backslashes

string = "//SQL-SERVER/Lacie/City of X/Linservo\\171002"
string.replace("\\","/")

Answer 4

You can simply use ".replace" in python or if you want you can use regex :

import re
string = r"//SQL-SERVER/Lacie/City of X/Linservo\171002"

pattern=r'[\\]'

replaced_string=re.sub(pattern,"/",string)

print(replaced_string)

Since your original question shows : "X/Linservo\\171002" here \\171 referring to character encoding so it's replacing \\171 to "y" . you can try this in python interpreter :

In[2]: print("\171")

y
