[python] pip install prettytable, 표 형태로 데이터를 보여준다. 

pip install prettytable

시각적으로 매력적인 ASCII 테이블 형식으로 표 형식의 데이터를 쉽게 표시하기 위한 간단한 Python 라이브러리

A simple Python library for easily displaying tabular data in a visually appealing ASCII table format

from prettytable import PrettyTable

# Create a PrettyTable object
table = PrettyTable()

# Define the table's columns
table.field_names = ["Name", "Age", "City"]

# Add rows to the table
table.add_row(["Alice", 30, "New York"])
table.add_row(["Bob", 25, "Los Angeles"])
table.add_row(["Charlie", 35, "Chicago"])

# Print the table
print(table)

# HTML 형식으로 테이블 표시

# HTML 형식으로 테이블 표시
# PrettyTable은 HTML 형식으로 테이블을 인쇄합니다 <table>. ASCII 형식과 마찬가지로 실제로 문자열 표현을 얻을 수 있습니다 
# get_html_string(). . HTML 인쇄는 ASCII 인쇄 와 동일한 방식으로 fields, start, 및 인수를 지원합니다.

print('\n\n',table.get_html_string(attributes={"id":"my_table", "class":"red_table"}))

전역 NaN 속성은 Not-A-Number(숫자가 아님)를 나타냅니다.

function sanitise(x) {
  if (isNaN(x)) {
    return NaN;
  }
  return x;
}

console.log(sanitise('1'));
// Expected output: "1"

console.log(sanitise('NotANumber'));
// Expected output: NaN

    initial_index = (ord(ch) - 0xAC00) // (21 * 28)
