读取文件内容时No such file or directory: 'star.txt'

Check if current working directory, os.getcwd(), to confirm if it is same directory for your star.txt.

>>> import os
>>> os.getcwd()
'C:\\Software\\python\\Lib\\idlelib'Copy

If not, you should add the path to the star.txt file to tell python where to find your file.

file_name = "C:/Users/jjy_0/star.txt"Copy

新手建议把这个去掉

file_name = "C:/Users/jjy_0/censuspopdata.xlsx"

import os os.getcwd () 'C:\Users\jjy_0\AppData\Local\Programs\Python\Python312' file_path = 'C:/Users/jjy_0/censuspopdata.xlsx' # 修正了文件扩展名前的空格，并确保大小写正确

try:
with open (file_path, 'rb') as file: # 使用 'rb' 模式读取二进制文件，如 PDF
content = file.read()
print ("文件内容已读取。") # 处理 content，例如保存到变量或进行其他操作

except FileNotFoundError:
print (f"无法找到文件: {file_path}") import openpyxl wb = openpyxl.load_workbook ('censuspopdata.xlsx') 最后使用了这个，七拼八凑版的，有前边 Jason 的功劳。（>0<）
