PIP e PIPETTE

Como calcular o valor de um pip 

Como cada moeda tem seu próprio valor relativo, é necessário calcular o valor de um pip para esse par de moeda particular. 

No exemplo a seguir, usaremos uma cotação com 4 casas decimais. 

Com o objetivo de explicar melhor os cálculos, as taxas de câmbio serão expressas como uma relação (ou seja, EUR / USD em 1.2500 será escrito como '1 EUR / 1.2500 USD')

 Exemplo 1: USD / CAD = 1.0200 

Para ser lido como 1 USD a 1.0200 CAD (ou 1 USD / 1.0200 CAD) 

(A mudança de valor em moeda contadora) vezes a taxa de câmbio = valor de pip (em termos de base moeda) 

[.0001 CAD] x [1 USD / 1.0200 CAD]

sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 1, and there are 74 supplied

You need to pass in a sequence, but you forgot the comma to make your parameters a tuple: cursor.execute('INSERT INTO images VALUES(?)', (img,)) Without the comma, (img) is just a grouped expression, not a tuple, and thus the img string is treated as the input sequence. If that string is 74 characters long, then Python sees that as 74 separate bind values, each one character long. >>> len(img) 74 >>> len((img,)) 1 If you find it easier to read, you can also use a list literal: cursor.execute('INSERT INTO images VALUES(?)', [img]) Originally published at stackoverflow.com .

Texto e código retirado deste site . I’m trying to “scrape” images from Imgur using BeautifulSoup and requests but I’m only getting the first page of results. Why? The example URL we’re given is  http://imgur.com/r/funny The code uses  requests  to fetch the HTML and  BeautifulSoup  with  html5lib  to parse it. If you don’t have these install already you can use install them using  pip  e.g. pip install beautifulsoup4 requests html5lib --user One thing to note is that  imgur.com has an api . You use it, taking the blue pill—the article ends. You take the red pill—you stay in Wonderland, and I show you how deep a  JSON  response goes. Remember: all I’m offering is the truth. Nothing more. “Developer Tools” Usually the first step to take is to debug the page in question inside your browser using the  “Developer Tools”  (although currently it seems to called  “Web Developer”  in  F...
