Definition of Python 3 string
Python 3 string are one of Python’s most common data types. Simply wrapping characters in quotations allows us to construct them. Variable value assigning is the same as creating strings. Because Python lacks a character type, these are handled as one-length strings and thus considered substrings. To get a substring, use index or indices. These functions make it simple to manipulate strings.
What is Python 3 string?
- The string data type in Python contains several built-in functions. These functions make it simple to change and manipulate strings. Functions are actions that we do on code elements. Built-in functions are those that are a specified language of python programming immediately accessible to us.
- The functions string lower and string upper return a string that has all of the letters in an original string changed to upper or lower case letters.
Python 3 string Characters
- Instances and exceptions are the main built-in types. Mutable collection classes exist. Methods that don’t return a specific item but never return the collection instance itself, but instead return none.
- Several object types offer some actions; for example, almost all objects can be compared for equality, verified using the repr, or somewhat different str functions. When the print method writes an object, the function is utilized implicitly.
- A list of non-printable or escape characters rendered with backslash notation can be found below. In both single and double-quoted strings, the escape character is understood.
Below is python 3 string characters as follows.
1) \a – This character is used for alert or bell.
2) \b – This character is used for backspace.
3) \cx – This character is used for control-x
4) \C- x – This character is used for control-x
5) \e – This character is used for escape.
6) \f – This character is used for a form feed.
7) \M – \C-x – This character is used for meta control x.
8) \n – This character is used for newline.
9) \nnn – This character is used for a range of octal.
10) \r – This character is used for return for carriage.
11) \s – This character is used for giving space between two characters or words.
12) \t – This character is used for giving the tab between two characters or words.
13) \v – This character is used to give a vertical tab.
14) \x – This character is used for character-x.
15) \xnn – This is nothing but the hexadecimal notation. In that n is nothing but the range from 0 to 9.
The below example shows python 3 string characters as follows. In the below example, we have used \v, \t, and \n characters.
Code:
Py3str = "python \n 3 \t string"
print (Py3str)Output:
- When the preceding code is run, the above result is obtained. Now every single special character, right down to the final newline has been converted to its printed form. Also, NEWLINEs appear when a line ends with return of carriage or its escape code.
- The backslash isn’t considered a special character in raw strings. Every character we type into a raw string is preserved in the same format as when we first typed it.
- The below example shows string is preserved in the same format as when we first typed it.
Code:
print ('C:\\python 3 string')Output:
Python 3 String Operators
- These methods allow searching specific substrings in a number of different ways. If only start and end are supplied, the technique is applied to segment from start to end.
- Below is the string operator which was used in python is as follows.
1. Addition (+)
The below example shows the addition string operator as follows.
Code:
py = "Python " + "string"
print(py)Output:
2. Multiplication
This string operator is used to repeat the string many times as follows. The below example shows multiplication string operators as follows.
Code:
py = "python " * 5
print (py)Output:
3. Slice
This operator returns the character which was provided by the x character. The below example shows the slice string operator as follows.
Code:
py = "Python"
print(py [1])Output:
4. Range Slice
This operator returns the character which was provided by the x:y character.
Code:
py = "Python"
print (py [2:4])Output:
5. In
This operator returns true if x will exist in the string as follows.
Code:
py = "python"
print("p" in py)
print("h" in py)
print("a" in py)Output:
6. Not In
This operator returns true if x will not exist in the string as follows.
Code:
py = "python"
print("p" not in py)
print("h" not in py)
print("a" not in py)Output:
Formatting Operators
For percent is one of Python’s most useful tools. This operator is only applicable to strings, and it compensates for the lack of printf family functions in C.
Below is the string formatting operator which was used in python as follows.
1) %c – This is the string formatting character operator.
2) %s – This is string conversion which was used for formatting the string.
3) %i – This is nothing but the signed decimal integer.
4) %d – This is nothing but the signed decimal integer.
5) %u – This is nothing but the unsigned decimal integer.
6) %o – This is nothing but the octal integer.
7) %x – This is nothing but the hexadecimal integer in lowercase letters.
8) %X – This is nothing but the hexadecimal integer in uppercase letters.
9) %e – This is nothing but exponential notation.
10) %f – This is nothing but the floating point number.
11) %g – This is the shorter of %e and %f.
Below is the Python 3 string formatting operator example is as follows. In the below example, we are using %s and %d operators.
Code:
print ("ABC %d XYZ %s PQR")Output:
These methods allow to search specific substring in a number of different ways. If only start and end are supplied, the technique is applied to segment from start to end. Python 3 strings are one of Python’s most common data types. Simply wrapping characters in quotations allows us to construct them.
