The Python programming language provides built-in functions for encoding and decoding strings. Theencode()function converts a string into a byte string. To demonstrate this, open the Python interactive console and type the following code:
Intro to Programming: What Are Functions and Methods in Python? To demonstrate with an example, let's first create a simple DataFrame and then let's add a column to it. I will create a DataFrame that contains the starting character of a country name inside theLettercolumn, and the country...
To insert a Unicode character that is not part ASCII, e.g., any letters with accents, one can use escape sequences in their string literals as such: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>> "\N{GREEK CAPITAL LETTER DELTA}" # Using the character name '\u0394' >>> "...
