我正在使用NBA Draft数据框，该数据框可以从here获取并通过熊猫读取。
当我尝试将csv加载到DataFrame时，列会被切片吗？使用以下代码：
import pandas as pd
r = pd.DataFrame.from_csv('data/historical_projections.csv')
print r
结果：

所以..有没有办法（我无法让行列工作）将DataFrame呈现得尽可能干净？谢谢。
答案 0 :(得分：0)
您想在屏幕上看到整个数据框吗？看看四舍五入是否适合您的需求
r.round(2)
答案 1 :(得分：0)
为了减小数据帧输出的宽度，您可以尝试以下操作：
首先，按照this的答案建议对浮点数进行四舍五入。为此，您可以执行以下操作：
import pandas as pd
r = pd.DataFrame.from_csv('data/historical_projections.csv')
r = r.round(2)
print r
或者：
import pandas as pd
r = pd.DataFrame.from_csv('data/historical_projections.csv')
print r.round(2)
但是请注意，第二个选项不会保留您在r中所做的更改，而只会保留您的 print 舍入后的数字
如果这还不够，您可以使用.columns 减少列名的长度：
r.columns = ['Pos', 'ID', 'Draft Year', 'Proj SPM', 'Star', 'Starter', 'Role', 'Bust']
最终代码应如下所示：
import pandas as pd
r = pd.DataFrame.from_csv('data/historical_projections.csv')
r = r.round(2)
r.columns = ['Pos', 'ID', 'Draft Year', 'Proj SPM', 'Star', 'Starter', 'Role', 'Bust']
print r
