基本上,我想迭代每一行并想选择c1列的值(示例-在第一次迭代中,我将获得值10) 比起取c1的值,我想改变 raw [row [''c1]]改为XX(示例-我们得到10的值,现在我想将raw ['10']的值更改为XX
我尝试过:
import pandas as pd
inp = [{'c1':10, '10':100, '11':100, '12':100},
{'c1':11,'10':110, '11':100, '12':100},
{'c1':12,'10':120, '11':100, '12':100}] .
df = pd.DataFrame(inp)
10 11 12 c1
0 100 100 100 10
1 110 100 100 11
2 120 100 100 12
Expected Output ::
10 11 12 c1
0 XX 100 100 10
1 110 XX 100 11
2 120 100 XX 12
答案 0 :(得分:0)
您可以这样做:
res = df.copy()
for i in df.iterrows():
res.loc[i[0], str(i[1]['c1'])] = 'xx'
res
10 11 12 c1
0 xx 100 100 10
1 110 xx 100 11
2 120 100 xx 12
答案 1 :(得分:0)
不建议在大熊猫中圈起来,因为它很慢,但是如果需要的话:
for row in df.itertuples(index=True, name='Pandas'):
variable=getattr(row, "c1")
df.loc[row.Index, str(variable)]= 'XX'
print (df)
10 11 12 c1
0 XX 100 100 10
1 110 XX 100 11
2 120 100 XX 12
您也可以按字典循环:
for k, v in df['c1'].to_dict().items():
df.loc[k, str(v)] = 'XX'
