What to Focus On

  • Operators are special symbols which represent computation.
  • Values or variables are called operands.
  • Operators applied on operands form an expression.

  • Parentheses have the highest priority in arithmetic expressions.
  • Exponentiation is evaluated before other arithmetic operations.
  • Division, floor division, multiplication, and modulus are grouped together.

  • Relational operators include <, >, <=, >=, !=, <>, and ==.
  • They return True or False.
  • String comparison uses ASCII or ordinal values.

Common Mistakes to Avoid

String indexing starts from 1, so the first character has index 1.

A negative index is invalid in Python strings.

If a string index is out of range, Python returns nothing or the last character.
