Python CSV文件按列排序

我有一个.CSV文件：

0.04081632653061224,0.02209708691207961,0.02040816326530612,0.02209708691207961

如何按列排序

例如：

速度
0.04081632653061224
0.02209708691207961
0.02040816326530612
0.02209708691207961

我建议使用熊猫来实现这一点。可以通过运行

pip install

来安装它。然后运行以下脚本：

Import pandas as pd
x = pd.read_csv("foo.csv")
x = x.sort_values(by=["Velocity"], ascending=False)
x.to_csv("sorted_foo.csv")

只需将文件作为字符串读取并用逗号分隔即可

data = "0.02209708691207961,0.02040816326530612,0.02209708691207961,0.04081632653061224"

datalist = [ float(x) for x in data.split(",") ]
datalist.sort(reverse=True)

print(datalist)
