Up to this point, you’ve learned how to suppress the meaning of a given character by escaping it. Suppose you need to create a string containing a tab character. Some text editors may allow you to insert a tab character directly into your code. However, this is considered a poor ...
python之模块 模块,用一砣代码实现了某个功能的代码集合。 类似于函数式编程和面向过程编程,函数式编程则完成一个功能,其他代码用来调用即可,提供了代码的重用性和代码间的耦合。而对于一个复杂的功能来,可能需要多个函数才能完成(函数又可以在不同的.py文件中),n个 .py 文件组成的代码集合就称为模块。 如:os ...

However, to be safe, it may be good to sanitize strings with normalize('NFC', user_text) before saving. NFC is also the normalization form recommended by the W3C in Character Model for the World Wide Web: String Matching and Searching. Some single characters are normalized by NFC into ...

Else, If the character is not upper-case, keep it with no change. Let us now look at the code: shift = 3 # defining the shift count text = "HELLO WORLD" encryption = "" for c in text: # check if character is an uppercase letter ...
