This article mainly explains "what are the escape characters of the Python string". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn what the escape characters of the Python string are.

What is an escape character

Escape character refers to replacing some special characters with a combination of ordinary characters, which is called "escape" because the combination changes the meaning of the original characters.

To put it simply, it is the function of transforming a character into another meaning, so we call it "escape character".

The meaning of escape characters is to avoid ambiguity and system recognition errors.

For example, to print "PHP is the most beautiful language in the world"

Print ("PHP is the most beautiful language in the world") print ("PHP is the most beautiful language in the world") print ("\" PHP is the most beautiful language in the world\ ")

Escape is generally to prevent conflicts with key characters of the program, for example, a paragraph of text within double quotation marks also has double quotation marks, then it is necessary to escape the double quotation marks of the text.

Escape characters in Python

Examples are as follows:

Info_n = "my name\ nis Neo" print ("n", info_n) info_t = "my name\ tis Neo" print ("t", info_t) info_v = "my name\ vis Neo" print ("v", info_v) # execute info_a = "my name\ ais Neo" print ("a") on the Terminal terminal Info_a) # execute info_b = "my name is Neo\ b" print ("b", info_b) info_r = "my name is Neo\ r" print ("r", info_r, info_b) info_f = "my name is Neo\ f" print ("f") at the Terminal terminal Info_f) # execute print ("My name is\ 'Neo\'") print ("My name is\" Neo\ "") escape invalid character on the Terminal terminal

In Python, add r before the string to invalidate the escape character of the current string

Print (r "My name is\" Neo\ "")

The implementation results are as follows:

> > My name is\ "Neo\"
