[Developer benefits] The most comprehensive free material collection and material collection on mobile terminals In today's surging mobile design, mobile UI and UX designers have a long way to go. Clever women are hard to cook without rice. Good materials are the foundation of designers. The free materials collected on the mobile end are comprehensive, from teaching resources to UI Kit, from development tools to icon collection.

This question is one of the problems I encountered when I was learning udacity (a web-based course platform) to learn the Web Development course: The topic is probably to define a ROT13 function, and then convert the input letter to the corresponding 13 position of the letter, such as input hello, output should be urryb, the case is unchanged, the other symbols unchanged. Instinctively think of a corresponding two-tuple list to map: The zip used here,

is the first project of the Udacity course. The idea is to make a comparison of the size of Texas poker.First, you abstract a processing function, which gives the result based on the size of the return value. After we've defined how to compare the sizes of two or more hands, to make it easier to compare sizes, we first preprocess 5 cards and sort them in descending order, as follows: def card_ranks (hand): ranks = ['--23456789tjqka '.

Read SICP, the little schemer. These can make you understand why computing is a science, and writing code is not. Just as architecture is a science, and walls are not.
