This post is part of a series that will teach you to use Python if you come from Java. I highly recommend you start from here if you don’t know o only has a little bit of Python knowledge. Let’s begin.
Java and Python share some common primitive types, but there are notable differences between them. Let’s take a look at the Python and Java data types.

Numeric Integer data types
In Python, the numeric primitive types byte, short, and long do not exist. Instead, you can use the int data type, which can represent integers of arbitrary size.
For the numeric primitive char type, Python does not have a direct equivalent. Instead, it has the str type, which represents strings. It’s important to note that char is not numeric in Python; it is treated as a single-character string.

Numeric Float data types
The primitive numeric float data type double does not exist in Python. Instead, Python uses the float data type, which is equivalent to Java’s double (64-bit floating point).

Boolean data types
The boolean primitive data type stores true and false values in both Java and Python. However, in Python, these values are capitalized as True and False, while in Java, they are lowercase as true and false.
The next comparison table of Java and Python types:
| Java Primitive Type | Python Type | Description |
|---|---|---|
byte | int | Java’s byte (8-bit) is an integer. Python’s int type can represent any integer size. |
short | int | Java’s short (16-bit) is also represented by Python’s int, which handles arbitrary precision. |
int | int | Java’s int (32-bit) is directly comparable to Python’s int, which scales beyond 32 bits. |
long | int | Java’s long (64-bit) corresponds to Python’s int, which can represent very large integers. |
float | float | Java’s float (32-bit floating point) maps to Python’s float, which is a 64-bit floating point. |
double | float | Java’s double (64-bit floating point) also maps to Python’s float. Python only has one floating-point type, which is equivalent to Java’s double. |
char | str | Java’s char (16-bit Unicode character) maps to Python’s str type, which represents strings as sequences of Unicode characters. |
boolean | bool | Both Java’s boolean and Python’s bool represent two values: true/false in Java and True/False in Python. |

Key Differences
Key Differences:
- Java: Primitive types are fixed in size, meaning they consume a specific amount of memory (e.g.,
intis 32 bits). - Python: Types like
intandfloatare dynamically sized, meaning they can grow as needed. This flexibility comes at the cost of performance and memory efficiency in some cases. - Python: The primitive data types are just called as data types.
As you can see both are similar even you have less primitive data types in Python than Java. However, Python has more data types.
Happy Learning!!!
