This is the desired dictionary that I want to create

trade_stocks_dic = {datetime.date(2021,1,1) : [{'ACC': {'High':800,'Low':200}},{'TCS': {'High':1000,'Low':250}},{'RELIANCE': {'High':134,'Low':20}}] }

Here is my code

for stock in all_stocks:

data = {}
data[datetime.date(2012,1,2)] = []
data[datetime.date(2012,1,2)].append(data[stock]={'High':10,'Low':20})

It is giving me SyntaxError: keyword can't be an expression

The exception has obviously told you that your keyword, which means your value, cannot be an expression. That is, you cannot give dict keyword such that:

data['a'].append(True = False)

Also, you have a bug in your initialization. If you do so, you will clear your data dictionary every iteration. The correction of the code should be above:

data = {}
all_stocks = ["ACC","TCS","RELIANCE"]
for stock in all_stocks:
    if datetime.date(2012,1,2) not in data:
        data[datetime.date(2012,1,2)] = [{stock: {'High':10,'Low':20}}]
    else:
        data[datetime.date(2012,1,2)].append({stock: {'High':10,'Low':20}})
