  Operators are used to perform operations on variables and values. Python divides the operators in the following groups: Arithmetic operators Assignment operators Comparison operators Logical operators Identity operators Membership operators Bitwise operators Python Arithmetic Operators Arithmetic operators are used with numeric values to perform common mathematical operations: Operator Name Example Try it + Addition x + y Try it » - Subtraction x - y Try it » * Multiplication x * y Try it » / Division x / y Try it » % Modulus x % y Try it » ** Exponentiation x ** y Try it » // Floor division x // y Try it » Python Assignment Operators Assignment operators are used to assign values to variables: Operator Example Same As Try it = x = 5 x = 5 Try it » += x += 3 x = x + 3 Try it » -= x -= 3 x = x - 3 Try it » *= x *= 3 x = x * 3 Try it » /= x /= 3 x = x / 3 Try it » %= x %= 3 x = x % 3 Try it » //= x //= 3 x = x // 3 Try it » **= x **= 3 x = x ** 3 Try it » &= x &= 3 x = x &

add() Adds an element to the set clear() Removes all the elements from the set copy() Returns a copy of the set difference() Returns a set containing the difference between two or more sets difference_update() Removes the items in this set that are also included in another, specified set discard() Remove the specified item intersection() Returns a set, that is the intersection of two other sets intersection_update() Removes the items in this set that are not present in other, specified set(s) isdisjoint() Returns whether two sets have a intersection or not issubset() Returns whether another set contains this set or not issuperset() Returns whether this set contains another set or not pop() Removes an element from the set remove() Removes the specified element symmetric_difference() Returns a set with the symmetric differences of two sets symmetric_difference_update() inserts the symmetric differences from this set and another union() Return a set containing the union of sets update() U

# Create a dictionary and take input from the user and return the meaning of the # word from the dictionary Dict = {"ignore":"refuse to take notice of or acknowledge", "abandon":"cease to support or look after",         "exaggerate":"enlarged or altered beyond normal proportions", "prejudice":"preconceived opinion that is not based on reason or actual experience"} print("Enter the Word") Data1 = input() print(Data1, "means", Dict[Data1])

clear() Removes all the elements from the dictionary copy() Returns a copy of the dictionary fromkeys() Returns a dictionary with the specified keys and value get() Returns the value of the specified key items() Returns a list containing a tuple for each key value pair keys() Returns a list containing the dictionary's keys pop() Removes the element with the specified key popitem() Removes the last inserted key-value pair setdefault() Returns the value of the specified key. If the key does not exist: insert the key, with the specified value update() Updates the dictionary with the specified key-value pairs values() Returns a list of all the values in the dictionary
