Returns a string padded with fillchar with the original string centered to a total of width columns.Ĭounts how many times str occurs in string or in a substring of string if starting index beg and ending index end are given.ĭecode(encoding = 'UTF-8',errors = 'strict')ĭecodes the string using the codec registered for encoding. Python includes the following built-in methods to manipulate strings − Sr.No. In Python 3, all strings are represented in Unicode.In Python 2 are stored internally as 8-bit ASCII, hence it is required to attach 'u' to make it Unicode. Every character you put into a raw string stays the way you wrote it − Raw strings do not treat the backslash as a special character at all. TAB ( ) and they will show up that way when displayed.
ELEMENTS OF PROGRAMMING INTERVIEWS ADD OPERATORS IN STRING CODE
Also note that NEWLINEs occur either with an explicit carriage return at the end of a line or its escape code (\n) − Note how every single special character has been converted to its printed form, right down to the last NEWLINE at the end of the string between the "up." and closing triple quotes. When the above code is executed, it produces the following result. The variable assignment will also show up. This within the brackets, or just a NEWLINE within NEWLINEs within the string, whether explicitly given like TAB ( \t ) and they will show up that way when displayed. Several lines and non-printable characters such as Para_str = """this is a long string that is made up of The syntax for triple quotes consists of three consecutive single or double quotes. Python's triple quotes comes to the rescue by allowing strings to span multiple lines, including verbatim NEWLINEs, TABs, and any other special characters. M is the minimum total width and n is the number of digits to display after the decimal point (if appl.) '%%' leaves you with a single literal '%' Pad from left with zeros (instead of spaces) Leave a blank space before a positive numberĪdd the octal leading zero ( '0' ) or hexadecimal leading '0x' or '0X', depending on whether 'x' or 'X' were used. Other supported symbols and functionality are listed in the following table − Sr.No. String conversion via str() prior to formattingĮxponential notation (with lowercase 'e')Įxponential notation (with UPPERcase 'E') Here is the list of complete set of symbols which can be used along with % − Sr.No. Print ("My name is %s and weight is %d kg!" % ('Zara', 21)) This operator is unique to strings and makes up for the pack of having functions from C's printf() family. One of Python's coolest features is the string format operator %. Print r'\n' prints \n and print R'\n'prints \n The "r" can be lowercase (r) or uppercase (R) and must be placed immediately preceding the first quote mark. The syntax for raw strings is exactly the same as for normal strings with the exception of the raw string operator, the letter "r," which precedes the quotation marks. Raw String - Suppresses actual meaning of Escape characters. Membership - Returns true if a character does not exist in the given string Membership - Returns true if a character exists in the given string Range Slice - Gives the characters from the given range Slice - Gives the character from the given index Repetition - Creates new strings, concatenating multiple copies of the same string
Hexadecimal notation, where n is in the range 0.9, a.f, or A.FĪssume string variable a holds 'Hello' and variable b holds 'Python', then − OperatorĬoncatenation - Adds values on either side of the operator
Octal notation, where n is in the range 0.7
When the above code is executed, it produces the following result −įollowing table is a list of escape or non-printable characters that can be represented with backslash notation.Īn escape character gets interpreted in a single quoted as well as double quoted strings. Print ("Updated String :- ", var1 + 'Python')
