How do you insert a symbol in python?

It is, however, possible to create a new string that has the inserted character:

However if you like something like a function do as this:

2 As strings are immutable another way to do this would be to turn the string into a list, which can then be indexed and modified without any slicing trickery. However, to get the list back to a string you'd have to use
I am not sure how this compares as far as performance, but I do feel it's easier on the eyes than the other solutions. ;-) answered Mar 10, 2011 at 1:48

If the index pos_i is very small (too negative), the insert string gets prepended. If too long, the insert string gets appended. If pos_i is between -len(string_s) and +len(string_s) - 1, the insert string gets inserted into the correct place. answered Feb 7, 2020 at 1:57

enomadenomad 9838 silver badges16 bronze badges 1 How do you type special characters in Python?In Python strings, the backslash "\" is a special character, also called the "escape" character. It is used in representing certain whitespace characters: "\t" is a tab, "\n" is a newline, and "\r" is a carriage return. Conversely, prefixing a special character with "\" turns it into an ordinary character.
What is the %% in Python?The % symbol in Python is called the Modulo Operator. It returns the remainder of dividing the left hand operand by right hand operand. It's used to get the remainder of a division problem.
How do you print special symbols in Python?Use repr() to print special characters. a_string = "\nString\n". literal_string = repr(a_string). print(literal_string). How do I find the symbol in Python?Python Program to check special characters. Input: "Hello!!". Output: string is not accepted.. Input: "hello123". Output: string is accepted.. Step 1- Import re module.. Step 2- Define a function to check for special characters.. Step 3- Create a regular expression of all the special characters.. |
