我有下面的excel表可在此处下载。
对于熊猫，我是这样读的：
import pandas as pd
infile = "sample1_neu_input_deconv.xlsx"
outdf = pd.read_excel(infile)
outdf.head()
看起来像这样：
In [8]: outdf.head()
Out[8]:
ID_REF Gene.Symbol GSM1711905 GSM1711906 GSM1711907
0 10344620 Gm10568 78.496 70.582 78.496
1 10344622 Gm10568 87.940 85.746 94.670
2 10344624 Lypla1 324.306 450.037 231.723
3 10344633 Tcea1 361.733 758.949 917.704
4 10344637 Atp6v1h 236.272 275.910 453.972
现在我要做的是用以下命令剥离Gene.Symbol列并使其大写：
outdf["Gene.Symbol"].map(str.strip).map(str.upper)
但它给了我以下错误：
TypeError: descriptor 'strip' requires a 'str' object but received a 'unicode'
正确的方法是什么？
您可以连锁连续的矢量化str调用来实现您想要的：
In [4]:
outdf['Gene.Symbol'] = outdf['Gene.Symbol'].str.strip().str.upper()
outdf['Gene.Symbol']
Out[4]:
