In this chapter, I am going to show you all how to create a python variable. <\/p>\n
Python variable does not have a fixed type which means you can actually change the variable type by first assigning it to a number but later changing it to a string, Python will not complain about this!<\/p>\n
\r\naname = "Hello, World"\r\nprint(aname) # Hello World\r\naname = 10\r\nprint(aname) # 10\r\n<\/pre>\nIf you want to use the Python variable which is outside of a function within that function itself then you will need to declare it as a global variable within the function.<\/p>\n
\r\nvalue = 5\r\ndef print_value():\r\n global value\r\n value += 1\r\n print(value) # increase the value of a variable by 1 which is equal to 6\r\n<\/pre>\nYou can specify the data type of a variable with casting but basically, it is the same outcome as before if you change it later to a string because Python does not have type safety like Java or C!<\/p>\n
\r\nvalue = int(10)\r\nprint(value) # 10\r\nvalue = 13\r\nprint(value) # 13\r\nvalue= "Hello World!"\r\nprint(value) # Hello World!\r\n<\/pre>\nThat is it, I will start to load you with a complex tutorial but as always let us starts it with this easy one first!<\/p>\n","protected":false},"excerpt":{"rendered":"
