Python data structures include lists, tuples, dictionaries, and sets.

• Lists: Ordered, mutable, can contain duplicate elements. Example: [1, 2, 3]

• Tuples: Ordered, immutable, can contain duplicate elements. Example: (1, 2, 3)

• Dictionaries: Unordered, mutable, key-value pairs. Example: {'key': 'value'}

• Sets: Unordered, mutable, no duplicate elements. Example: {1, 2, 3}

Python data structures are collections of data that allow for efficient storage and manipulation.

• Python lists: ordered, mutable, can contain different data types

• Python tuples: ordered, immutable, can contain different data types

• Python sets: unordered, mutable, no duplicate elements

• Python dictionaries: unordered, mutable, key-value pairs

Java programs can be used to check logical conditions and expressions.

• Use if-else statements to check logical conditions

• Use logical operators such as && (and), || (or), and ! (not)

• Use switch statements for multiple conditions

• Use ternary operator for simple conditions

• Example: if(x > y && z < 10) { // do something }

• Example: switch(dayOfWeek) { case 1: // do something; break; default: // do something else; }
