Python：No such file or directory

Question

问题遇到的现象和发生背景

Python小白，这学期末要交一个python作业，但是写好代码反复出现以下问题，求大佬解答。

问题相关代码，请勿粘贴截图

import pandas as pd
import numpy as np

#剔除治疗方式为空的记录
df = pd.read_excel("数据表格_25.xlsx", sheet_name="公式与函数", index_col=False)
df.dropna()
df.to_excel("数据表格_25_2.xlsx", sheet_name="公式与函数")

#计算不同治疗方式对应的用药天数的均值
df = pd.read_excel("数据表格_25.xlsx", sheet_name="公式与函数", index_col=False)
mean_M1 = 0
count_M1 = 0
mean_P1 = 0
count_P1 = 0
for i in df.index:
each_record = df.values[i]
if each_record[3] == "M1":
mean_M1 += each_record[4]
count_M1 += 1
if each_record[3] == "P1":
mean_P1 += each_record[4]
count_P1 += 1
print("治疗方式为P1的平均用药天数为：", int(mean_P1/count_P1))
print("治疗方式为M1的平均用药天数为：", int(mean_M1/count_M1))

运行结果及报错内容

我想要达到的结果

Answer 1

数据表格_25.xlsx 你这个文件的路径不对，你这个文件和 Python 脚本在同目录吗？

如果不是，建议你拷贝到同一个目录中，打开 windows 控制台，python 你的脚本名字，直接启动就好了
