5 Best Ways to Find Python String Length Python Pool
String indexing in Python is zero-based: the first character in the string has index 0, the next has index 1, and so on. The index of the last character will be the length of the string minus one. For example, a schematic diagram of the indices of the string 'foobar' would look like this: String Indices.
Python String length with Examples Spark By {Examples}
Python strings are length-prefixed, so their length is limited by the size of the integer holding their length and the amount of memory available on your system.Since PEP 353, Python uses Py_ssize_t as the data type for storing container length. Py_ssize_t is defined as the same size as the compiler's size_t but signed. On a 64 bit system, size_t is 64. 1 bit for the sign means you have 63.
