python - 如何在python中将一个函数的变量运行到另一个函数？

Question

我是初学者。我有两个功能:
第一个创建数据框和一些打印语句
第二是将数据帧下载到 colab 中的 csv。
我想通过 df_name 下载所有数据帧。
代码:

def fun1():
  import pandas as pd
  d = {'col1': [1, 2], 'col2': [3, 4]}
  d2 = {'col1': [-5, -6], 'col2': [-7, -8]}
  df = pd.DataFrame(data=d)
  df2 = pd.DataFrame(data=d2)
  print('info', df.info())
  print('info', df2.info())
  return df, df2
def fun2(df):
  from google.colab import files
  name1 = 'positive.csv'
  name2 = 'negative.csv'
  df.to_csv(name1)
  df2.to_csv(name2)
  files.download(name1)
  files.download(name2)

fun2(df) #looking something like this that download my df, func2 should read my df and df2 from fun1() 

我试过:

class tom:
  def fun1(self):
    import pandas as pd
    d = {'col1': [1, 2], 'col2': [3, 4]}
    d2 = {'col1': [-5, -6], 'col2': [-7, -8]}
    df = pd.DataFrame(data=d)
    df2 = pd.DataFrame(data=d2)
    print('info', df.info())
    print('info', df2.info())
    self.df= df
    self.df2 = df2
    
    return df, df2
 
  def fun2(self):
    df,df2 = fun1()
    from google.colab import files
    name1 = 'positive.csv'
    name2 = 'negative.csv'
    df.to_csv(name1)
    df2.to_csv(name2)
    return files.download(name1) ,files.download(name2)

tom().fun2() #it download files but shows print of fun1 as well which I don't want. 

寻找类似的东西

tom().fun2(dataframe_name) #it just download the files nothing else

如果它不会改变，直接在类中设置永久变量
只为行动定义乐趣。

class s:
  import pandas as pd
  
  d = {'col1': [1, 2], 'col2': [3, 4]}
  d2 = {'col1': [-5, -6], 'col2': [-7, -8]}
  df = pd.DataFrame(data=d)
  df2 = pd.DataFrame(data=d2)


  name1 = 'positive.csv'
  name2 = 'negative.csv'
  df.to_csv(name1)
  df2.to_csv(name2)
  def f():
    print('info', df.info())
    print('info', df2.info())
  
  def fun(x):
    from google.colab import files
    return files.download(x)

跑

s.f() --it will print value only
s.fun(s.name1) --it will just download the file
