I am trying to create the following dataset:
multiple_newbooks = {"Books'Tiltle":["American Tabloid", 'Libri che mi hanno rovinato la vita ed Altri amori malinconici', '1984' ],
'Authors':['James Ellroy', 'Daria Bignardi', 'George Orwell'],
'Publisher': [('Mondadori' for i in range(0,2)), 'Feltrinelli'],
'Publishing Year':[1995, 2022, 1994],
'Start': ['?', '?', '?'],
'Finish': ['?', '?', '?']}
As you could some data present some repetitions. I would just avoid using the .append
function outside the data frame I am creating for the 'Publisher' row
(since the code you see here does not work) or to avoid the following sequence of equal data:
'Start': ['?', '?', '?'],
'Finish': ['?', '?', '?']
Could you possibly know how to use alternative elegant and smart code? Thanks for your suggestions.
CodePudding user response:
If I understand you correctly, you don't want to repeat writing the strings. You can use for example *
to repeat the string:
multiple_newbooks = {
"Books'Tiltle": [
"American Tabloid",
"Libri che mi hanno rovinato la vita ed Altri amori malinconici",
"1984",
],
"Authors": ["James Ellroy", "Daria Bignardi", "George Orwell"],
"Publisher": ["Mondadori"] * 2 ["Feltrinelli"],
"Publishing Year": [1995, 2022, 1994],
"Start": ["?"] * 3,
"Finish": ["?"] * 3,
}
print(multiple_newbooks)
Prints:
{
"Books'Tiltle": [
"American Tabloid",
"Libri che mi hanno rovinato la vita ed Altri amori malinconici",
"1984",
],
"Authors": ["James Ellroy", "Daria Bignardi", "George Orwell"],
"Publisher": ["Mondadori", "Mondadori", "Feltrinelli"],
"Publishing Year": [1995, 2022, 1994],
"Start": ["?", "?", "?"],
"Finish": ["?", "?", "?"],
}
Or better:
multiple_newbooks = {
"Books'Tiltle": [
"American Tabloid",
"Libri che mi hanno rovinato la vita ed Altri amori malinconici",
"1984",
],
"Authors": ["James Ellroy", "Daria Bignardi", "George Orwell"],
"Publisher": ["Mondadori" for _ in range(2)] ["Feltrinelli"],
"Publishing Year": [1995, 2022, 1994],
"Start": ["?" for _ in range(3)],
"Finish": ["?" for _ in range(3)],
}
