openpyxl读写文件并做简单数据分析
为了使用openpyxl计算Excel表格中某一列的平均值,可以使用以下步骤:
1.导入openpyxl库并打开Excel文件:
```python
from openpyxl import load_workbook
wb = load_workbook(filename='example.xlsx')
ws = wb.active
```
2.确定要计算平均值的列,并将该列的值存储在一个列表中:
```python
col_values = []
for row in ws.iter_rows(min_row=2, min_col=2, max_col=2):
for cell in row:
col_values.append(cell.value)
```
3.计算列表中所有值的平均值:
```python
average = sum(col_values) / len(col_values)
```
4.将平均值输出到控制台:
```python
print("The average is:", average)
```
完整代码如下:
```python
from openpyxl import load_workbook
wb = load_workbook(filename='example.xlsx')
ws = wb.active
col_values = []
for row in ws.iter_rows(min_row=2, min_col=2, max_col=2):
for cell in row:
col_values.append(cell.value)
average = sum(col_values) / len(col_values)
print("The average is:", average)
```
