What are the advantages and disadvantages of dynamic typing in programming languages?

Dynamic typing means that the type of a variable is determined at runtime, not at compile time.

Advantages:

• Flexibility: you can easily change data types and write more versatile code.
• Rapid development: less code for declaring types and fewer restrictions.

Disadvantages:

• Type errors are detected only at runtime, which can lead to bugs.
• Loss of performance due to the need for type checks during program execution.
• Less support from static analysis tools and autocomplete.

Example in Python:

x = 10      # x is int
x = 'text'  # now x is str

Such code is impossible in statically typed languages without explicit conversion.
