Why does PyCharm display all information when reading an Excel file?

When PyCharm reads an Excel file, it displays all the information in the spreadsheet by default, including hidden rows and columns. This is to ensure that you can see all the data in the workbook.

Solution:

If you only want to display visible information, you can use the following method:

Manual method:

1. Select the rows or columns you want to hide.
2. Right click and select "Hide".

Use Python code:

import pandas as pd # 读取 Excel 文件 df = pd.read_excel('filename.xlsx', usecols='A:D', header=0) # 显示可见数据 df = df.dropna(how='all')

Detailed instructions:

• usecolsThe parameter specifies that only the data in columns A to D should be read.
• header=0The parameter specifies the header in line 0.
• dropna(how='all')Function drops all rows that are completely NaN.

Note:

• If there are formulas in the Excel file, errors may occur when reading it using Python.
• If the Excel file contains charts or other non-data elements, they will not be read by Python.
