Get name of List Item in python-CodePudding

I have a list of dataframes in python.

sensors = [df_x, df_y, df_z]

df_x, df_y, df_z are dataframes

How to get name of the dataframe?

Ex: df_x, df_y, df_z

CodePudding user response：

df_x = ['df_x', (variable)]
df_y = ['df_x', (variable)]    
df_z = ['df_x', (variable)]  
sensors = [df_x[1], df_y[1], df_z[1]]

if you want to know variable name in string, df_x[0] is that one.

CodePudding user response：

If a variable starts with df_ is a dataframe to you. You can use this.

# If the values of the list are strings
sensors = ['df_x', 'df_y', 'df_z']

for i in sensors:
    if i.startswith("df_"):
        print(f"{i} is a dataframe")
    print(f'{i} is not a dataframe')
