Rename Dataframe name python-CodePudding

I want to change the name of an dataframe using variables.

db = pd.Dataframe()

sopa = ['cebola','batata']


for sopa_id in sopa: 

    sopa_id = db

I want that the output to be:

 cebola = db

 batata = db

The goal is that each one of the variable get the dataframe name.

I start by saying that what you are doing is probably not good practice. This can probably be solved with dict.

Anyway I think locals() can come in handy.

for i in range(3):
    locals()["var" str(i)] = i
    
print(var0)
print(var1)
print(var2)

As you can see var0, var1 and var2 don't exist before the loop. You can find more Here!

For dynamic variable names in python, see How can you dynamically create variables?

The way to do it is to make a dictionary where the key is the name and the value is the dataframe db. I would discourage dynamic variable names as a general rule though.

db = pd.DataFrame()
# -- Do whatever here to populate --
sopa = ['cebola','batata']

dataframeDict = {}
for sopa_id in sopa:
    dataframeDict[sopa_id] = db

Thank you all, problem solved.

db = pd.Dataframe()

sopa = ['cebola','batata']


for sopa_id in sopa: 
    locals()["new_name_is_" str(sopa_id)] = db

best,
