Hello dear readers! Welcome back to another edition of our tutorial on Python. In this tutorial guide, we are going to be discussing about the Python Dictionary fromkeys() method.

The Python Dictionary fromkeys() method creates a new dictionary with keys from seq and values set to value.


The following below is the syntax for Python Dictionary fromkeys() method -

dict.fromkeys(seq[,  value] )

Parameter Details

  • seq - This is the list of values which would be used for dictionary keys preparation.
  • value - This is optional, if provided then value would be set to this value.

This method returns the list.


The following below is a simple example -

New Dictionary : {'age': 10, 'name': 10, 'sex': 10}
