Datatypes in Python...

 Basic datatypes  in python are

• String
• Integer
• Float
• Complex Numbers 
• Built-in datastructures 

1. list
2. tuple
3. set
4. dictionary

• Built-in methods on String:

stringname.capitalize() - First letter of string is converted in uppercase

stringname.casefold()  - Converts string into lower case

stringname.upper()-Coverts the whole string into uppercase.

stringname.lower()-Converts the whole string into lowercase.

stringname.count()- Prints the number of times a specific value is occurred

stringname.isnumeric() - Returs whether the values in string are numeric or not

stringname.isupper() - Returns whether the string is in uppercase or not i.e True or False

stringname.islower() - Returns whether the string is in lowercase or note i.e True or False

stringname.startswith("suffix") - Tells whether the string starts with particular suffix

stringname.endswith("prefix") - Tells whether the string ends with particular prefix

for more similar methods run print(dir("stringname"))

List

• Properties of List

List are ordered 

List are mutable

List are dynamic

List elements can be accessed by index

• Built-in methods of List

 listname.insert(index,element) - Inserts single element into the List at specific index

listname.append(element) - Inserts single element at end of the list.

listname.extend([element1,element2,element3,..,,]) - Inserts more than one elements

listname.remove(element) - removes particular element from list

listname.pop(index) - removes  element with particular index from the list.

listname.count(element) - returns the number of elements with specified values.

listname.reverse() - turns list into reverse order.

for more set methods run print(dir(listname))

Sets

• Properties of Sets

Sets are unordered.

Duplication of elements is allowed.

Set elements are unique.

Elements cannot be accessed using index.

• Built-in methods of Sets

setname.add(element) - adds single element into the set

setname.update([element1,element2,element3])- update the number of elements into the list

setname.remove(element) - Removes a particular element.

setname.pop()- pops a element from the set (It will pop any random element as its unordered)

for more set methods run print(dir(setname))

Dictionary

• Properties of Dictionary

More than one entry per key is not allowed.

Value of dictionary can be of any type.

• Built-in methods of Dictionary

dictname.keys()-  Returns all the keys from key value pair in dictionary

dictname.values() -Returns all the values from key value pair in dictionary

dictname.pop()-Pops elements with specific key-value pair

dictname.update({Key:value})- Updates the key value pair in dictionary

dictname.items()-Returns list containing tuple for each key value pair 

 for more set methods run print(dir(dictname))

Tuple

• Properties of Tuples

Indexing is allowed 

Tuples are Ordered

Duplication is allowed

Cannot be altered as immutable
