  1. STRING MANUPILATION

  2.    STRING OPERATORS TYPES OF STRING OPERATORS:- • BASIC OPERATORS • MEMBERSHIP OPERATORS • COMPARISON OPERATORS

  3. 1. BASIC OPERATORS THE TWO BASIC OPERATORS OF STRING ARE:- + AND *. YOU HAVE USED THESE ARITHMETRIC OPERATORS BEFORE FOR ADDITION AND MULTIPLICATION RESPECTIVELY. BUT WHEN USED WITH STRINGS, + OPERATOR PERFORMS CONCATENATION RATHER THAN ADDITION AND*OPERATOR PERFORMS REPLICATION RATHER THAN MULTIPLICATION. EXAMPLES:- • CONCATENATION:- str1 = 'Hello' str2 ='World!' print('str1 + str2 = ', str1 + str2) • REPLICATION:- str1 = 'Hello' str2 ='World!' print('str1 * 3 =', str1 * 3)

  4. 2. MEMBERSHIP OPERATORS THERE ARE TWO MEMBERSHIP OPERATORS FOR STRING .THESE ARE INAND NOT IN. • IN:- RETURNS TRUE IF A CHARACTER OR A SUBSTRING EXISTS IN THE GIVEN STRING; FALSE OTHERWISE.                          EX:- "A" in "HEYA"                                # RETURN TRUE • NOT IN:- RETURNS TRUEIF A CHARACTER OR A SUBSTRING DOES NOT EXIST IN THE GIVEN STRING; FALSE OTHERWISE.                          EX:- "jap" not in "JAPAN"                                # RETURN TRUE BECAUSE PYTHON IS CASE- SENSITIVE

  5. 3. COMPARISION OPERATORS Python string comparison is performed using the characters in both strings. The characters in both strings are compared one by one. When different characters are found then their Unicode value is compared. The character with lower Unicode value is considered to be smaller. EXAMPLES:- print(fruit1 == 'Apple')                #  TRUE print(fruit1 != 'Apple')                #  FALSE print(fruit1 < 'Apple')                 #  FALSE print(fruit1 > 'Apple')                 #  FALSE print(fruit1 <= 'Apple')               #  TRUE print(fruit1 >= 'Apple')               #  TRUE
