所以我有一个字典和一个带有已确定列的数据框。例如,我想将字典的每个第一个值放在第二列,并将每个第二个值放在最后一列。因此,我希望能够专门设置值。 这是我的字典和已经制作好的DataFrame:
products = {"Piano": [500, "10/10"],
"Table": [120, "9/10"],
"Book": [7, "2/10"]}
df = pd.DataFrame(columns=["Product Name", "Price", "Made in", "Product quality"])
我的图像类似:
df.column[1] = products["Piano"][0]
结果是:
Product Name Price Made in Product quality
Piano -- 500 -- 10/10
Table -- 9 -- 9/10
Book -- 2 -- 2/10
答案 0 :(得分:0)
pd.DataFrame.from_dict
和reindex
df = pd.DataFrame.from_dict(products, 'index', columns=['Price', 'Quality'])
df.reindex(columns=['Name', 'Price', 'MadeIn', 'Quality'])
Name Price MadeIn Quality
Piano NaN 500 NaN 10/10
Table NaN 120 NaN 9/10
Book NaN 7 NaN 2/10
