-characters-in-python gave the answer to a question in stackoverflow. When you print foo, what gets printed out is str(foo).However, if foo is a list, str(foo) uses repr(bar) for each element bar, not str(bar). Of course, this issue has long been discovered. In PEP3140 str (container) shocould call str (item), not repr (item), in this proposal, we recommend that you use _ str _ instead of _ repr _ when printing the container __. But Guido (father of Python) relentlessly refused because: Guido sa

Python reads and writes json files, JSON (JavaScript Object Notation) is a lightweight data exchange format. It is based on a subset of ECMAScript. JSON uses a completely language-independent text format, but it also uses a habit similar to the C language family (including C, C ++, Java, JavaScript, Perl, Python, and so on ). These features make JSON an ideal data exchange language. Easy to read and write, and easy to parse and generate by machines (generally used to increase the network transmi
