name.count (‘lex’) counts the number of occurrences of lex
name.encode () encodes a string into bytes
name.endswith ("Li") determines whether the string ends with Li
"Alex \ tLi" .expandtabs (10) outputs ‘Alex Li’, which converts \ t into how many spaces
name.find (‘A’) finds A, finds its index, returns -1 if not found

was hard to be updated, including the normal texture. The unzipped diffuse texture is about 64 MB, and 64 MB is also used for the normal texture. Imagine creating 10 or more textures on a computer with only 1 GB of memory, and the results would be terrible. Even if it is compressed into a dxt5 texture, the 4096x4096 normal texture still has about 12 Mb, Which is annoying when loading the texture alone. Another reason why I gave up using a 4096x4096 texture is the content pipeline in xNa, which
