Web21 jul. 2010 · Built-in scalar types¶. The built-in scalar types are shown below. Along with their (mostly) C-derived names, the integer, float, and complex data-types are also available using a bit-width convention so that an array of the right size can always be ensured (e.g. int8, float64, complex128).Two aliases (intp and uintp) pointing to the integer type that is … WebNotice the main difference: in C, the data types of each variable are explicitly declared, while in Python the types are dynamically inferred. This means, for example, that we can assign any kind of data to any variable: # Python code x = 4 x = "four". Here we've switched the contents of x from an integer to a string.
