我的问题类似于this one。我有一个包含一些合并单元格的电子表格,但包含合并单元格的列也有空单元格,例如:
namespace micro\controllers;
class ActiveController extends yii\rest\ActiveController {
public function behaviors() {
$behaviors = parent::behaviors();
$behaviors['contentNegotiator'] = [
'class' => 'yii\filters\ContentNegotiator',
'formats' => [
'application/json' => \yii\web\Response::FORMAT_JSON,
]
];
return $behaviors;
}
}
如何将其解析为 Pandas DataFrame?我知道 Day Sample CD4 CD8
----------------------------
Day 1 8311 17.3 6.44
--------------------
8312 13.6 3.50
--------------------
8321 19.8 5.88
--------------------
8322 13.5 4.09
----------------------------
Day 2 8311 16.0 4.92
--------------------
8312 5.67 2.28
--------------------
8321 13.0 4.34
--------------------
8322 10.6 1.95
----------------------------
8323 16.0 4.92
----------------------------
8324 5.67 2.28
----------------------------
8325 13.0 4.34
方法不会解决我的问题,因为它会用其他东西替换实际缺失的值。我想获得这样的 DataFrame:
fillna(method='ffill')
答案 0 :(得分:1)
假设您知道 excel 文件的起始行(或者想出更好的方法来检查),这样的事情应该可以工作
import pandas as pd
import numpy as np
import openpyxl
def test():
filepath = "C:\\Users\\me\\Desktop\\SO nonsense\\PandasMergeCellTest.xlsx"
df = pd.read_excel(filepath)
wb = openpyxl.load_workbook(filepath)
sheet = wb["Sheet1"]
df["Row"] = np.arange(len(df)) + 2 #My headers were row 1 so adding 2 to get the row numbers
df["Merged"] = df.apply(lambda x: checkMerged(x, sheet), axis=1)
df["Day"] = np.where(df["Merged"] == True, df["Day"].ffill(), np.nan)
df = df.drop(["Row", "Merged"], 1)
print(df)
def checkMerged(x, sheet):
cell = sheet.cell(x["Row"], 1)
for mergedcell in sheet.merged_cells.ranges:
if(cell.coordinate in mergedcell):
return True
test()
