I am new to python and i am trying to find size of int, float, double and char of my System. Do we have any syntax to find them?

take a look at [this](http://stackoverflow.com/questions/9860588/maximum-value-for-long-integer) question. – RickyA Dec 31 '13 at 13:52

3It sounds like you're asking about C/C++/Java/C#/... types, not about Python types. Please clarify. – Dec 31 '13 at 13:56

There is no such thing as `double` or `char` in Python. – Karl Knechtel Dec 31 '13 at 14:14

There is definitely types in python. You can check the type of a variable using the type(varname) command. – gautam1168 May 02 '18 at 03:07

You can look at sys.getsizeof. But it is more complicated than you may think.

Note the difference between `sys.getsizeof(int)` and `sys.getsizeof(int())` – wim Dec 31 '13 at 13:55

int technically has a finite size, but if the result of a computation goes past that size, Python will automatically use an arbitrary-precision long instead. Those are only limited by available memory.
float is an IEEE 64-bit binary floating-point number. Many other languages would call that a double.
double and char don't exist in Python. Python only has one built-in floating-point data type, which is float. Single-character strings are used to represent characters.

One can use ctypes.sizeof on ctypes' c_int, c_float, c_double, and c_char types respectively to find the size of the type in bytes.
