Python Datatypes
There are different types of data that you have to use in programming. Some are simple texts while others are integers or lists. Python supports a diversity of datatypes. However, you have to designate the datatype when you create one so that Python can recognize it easily and process it as per your wishes. In the following section, I will shed light on several data types that I will be using in various code snippets in the book. Datatypes, in a brief look, are as under: #This is Python list >>> a = ["tomato, potato, garlic, ginger, pumpkin"] >>> print(a) ['tomato, potato, garlic, ginger, pumpkin'] >>> #This is python frozenset >>> a = frozenset({"tomato, potato, garlic, ginger, pumpkin"}) >>> print(a) frozenset({'tomato, potato, garlic, ginger, pumpkin'}) >>> #This is python set >>> a = {"tomato, potato, garlic, ginger, pumpkin"} >>> print(a) {'tomato, potato, garlic, ginger, pumpkin'} >>> #This is python tuple >>> a = ("tomato, potato, garlic, ginger, pumpkin") >>> print(a) tomato, potato, garlic, ginger, pumpkin >>> #This is a dictionary >>> a = {"fruit" : "tomato", "veg: potato", "veg" : "garlic", "veg" : "ginger", "veg" : "pumpkin"} SyntaxError: invalid syntax >>> a = {"fruit" : "tomato", "veg": "potato", "veg" : "garlic", "veg" : "ginger", "veg" : "pumpkin"} >>> print(a) {'fruit': 'tomato', 'veg': 'pumpkin'} >>> a = {"fruit" : "tomato", "veg: potato", "veg1" : "garlic", "veg2" : "ginger", "veg3" : "pumpkin"} SyntaxError: invalid syntax >>> a = {"fruit" : "tomato", "veg": "potato", "veg1" : "garlic", "veg2" : "ginger", "veg3" : "pumpkin"} >>> print(a) {'fruit': 'tomato', 'veg': 'potato', 'veg1': 'garlic', 'veg2': 'ginger', 'veg3': 'pumpkin'} In the above I have turned a string into different datatypes. In the dictionary section of the code, you will see some errors. One error is because of a missing quote marks while the other error is because of similar dictionary names. Dictionaries are important as they allow users to store their important data in the form of pairs. They are used in a number of ways. Download 1.25 Mb. Do'stlaringiz bilan baham: |
