Question

I hae a dictionary like this

dict1 = [('var1','aa'),('var2','bb')('var3','cc')]

I have another dictionary

dict2 = [('var2','22'),('var3','33'),('var5','23'),('var6','33'),('var7','23')]

What i want to do is that i to replace the contents of dict2 with the varibels in dict1

I mean so that final dict3 = dict2 = [('var2','bb'),('var3','cc'),('var5','23'),('var6','33'),('var7','23')]

Answer 1

>>> list1 = [('var1','aa'),('var2','bb'),('var3','cc')]
>>> list2 = [('var2','22'),('var3','33'),('var5','23'),('var6','33'),('var7','23')]
>>> dict1 = dict(list1)
>>> list2 = [(k, dict1.get(k, v)) for k, v in list2]
>>> list2
[('var2', 'bb'), ('var3', 'cc'), ('var5', '23'), ('var6', '33'), ('var7', '23')]

This will maintain order from the original list2
