PANDAS：從csv文件導入數據時列名稱錯誤

Question

我通過以下代碼得到錯誤的列名：為什么會這樣？ 還有其他方法嗎？

names = {'SYMBOL','CLMP'}
data2 = pd.read_csv(filePath +"\\"+ fileNameCM2+'.csv',skiprows = 1, index_col=False, names = names,header=None)
df3 = pd.DataFrame(data2)

print(df3.head())

OUTPUT:
          CLMP    SYMBOL
0         ACC    853921
1    ADANIENT   2758466
2  ADANIPORTS   7591819
3  ADANIPOWER  11774513
4  AJANTPHARM    257752

EXPECTED:
      SYMBOL      CLMP
0         ACC    853921
1    ADANIENT   2758466
2  ADANIPORTS   7591819
3  ADANIPOWER  11774513
4  AJANTPHARM    257752

Answer 1

這是因為set將對名稱進行排序，而是使用列名稱list ：

names = ['SYMBOL','CLMP']
df3 = pd.read_csv(filePath +"\\"+ fileNameCM2+'.csv',
                  skiprows = 1, 
                  index_col=False, 
                  names = names)

print (df)
       SYMBOL      CLMP
0         ACC    853921
1    ADANIENT   2758466
2  ADANIPORTS   7591819
3  ADANIPOWER  11774513
4  AJANTPHARM    257752
