[英]How do you iterate over float excel columns in python?
Say I have an imported excel sheet that looks like this:假设我有一张进口的 excel 表,如下所示:
A B C D
4.296178, 0.434362, 0.033033, 2.758968
0.296178, 0.434362, 0.033033, 0.758968
3.396178, 0.434362, 0.033033, 1.758968
And I want to iterate through it in a way that returns the sum of each column, how would I do this?我想以一种返回每列总和的方式遍历它,我该怎么做?
I have tried this:我试过这个:
import openpyxl
templist = []
Col_one_total = []
Col_two_total = []
Col_three_total = []
for row in sheet.rows:
Col_one_total += row[0].value
Col_two_total += row[1].value
Col_three_total += row[2].value
templist.append(Col_one_total)
templist.append(Col_two_total)
templist.append(Col_three_total)
return max(templist)
but I keep getting an error saying TypeError: 'float' object is not iterable
.但我不断收到错误
TypeError: 'float' object is not iterable
。 Does anyone know how to resolve this?有谁知道如何解决这个问题?
I recommend using Pandas to do this.我建议使用 Pandas 来执行此操作。 The following code reads in the Excel file using the
read_excel
method and the sums each column using the sum
dataframe method.以下代码使用
read_excel
方法读取 Excel 文件,并使用sum
dataframe 方法对每列求和。
import pandas as pd
df = pd.read_excel('test.xlsx')
column_sums = df.sum()
print(column_sums)
Output: Output:
A 7.988534
B 1.303086
C 0.099099
D 5.276904
dtype: float64
Note: You need to have openpyxl
installed for this to work.注意:您需要安装
openpyxl
才能正常工作。 Else you'll run into the following error: ImportError: Missing optional dependency 'openpyxl'. Use pip or conda to install openpyxl.
否则你会遇到以下错误:
ImportError: Missing optional dependency 'openpyxl'. Use pip or conda to install openpyxl.
ImportError: Missing optional dependency 'openpyxl'. Use pip or conda to install openpyxl.
