Type conversion

Learn type conversions with int(), str(), float().

Converting a value to another type is called type conversion. The functions int(), float(), str(), bool() are used:

age_str = "25"
age = int(age_str)     # 25 (int)
price = float("19.99")  # 19.99 (float)

If the conversion fails Python raises ValueError: int("text") errors. So check the data before converting.

Automatic and explicit conversion

Python converts types automatically in some operations: 5 + 2.0 → 7.0. This is implicit conversion.

In explicit conversion you call a function: int("25"). Explicit conversion is safer and clearer about intent.

When comparing mixed types prefer explicit conversion: int(user_input) > 18.

Assign "25" to age_str. Assign int(age_str) to age. Then print print(age).

Show example solution

age_str = "25"
age = int(age_str)
print(age)
