Like every programming language, Python also have keywords(Reserved Words). you can not use them as a variable name or any other identifier name.
Python Keywords List
Python Keywords are used to perform an internal operation. All the keywords of Python contain lower-case letters only.
A variable is a named memory allocation which may vary at the time of execution.
Here x is an int type of variable and the value 100 is assigning to x.
Unlike other programming languages, there is no required to specify any data type explicitly to declare a variable.
y=12.34 z=”Mama” print(y) print(z) Output: 12.34 Mama
x1 = 100 # x1 is of type int
x1 = "Silan" # x1 is now of type str
Here String variables can be declared either by using single or double or triple quotes. For ex;
x2 = "Silan"
# is the same as
x2 = 'Silan'
mydata = "Silan"
my_data = "Silan"
_my_data = "Silan"
myData = "Silan"
MYDATA = "Silan"
mydata1 = "Silan"
1mydata = "Silan"
my-data = "Silan"
my data = "Silan"
#Variable manipulation t1=100 t2=12.34 s1="Silan" s2="Tutorial" print(t1) print(t2) print(s1) print(s2) Output: 100 12.34 Silan Tutorial
t1+t2 Output: 112.34
s1+s2 Output: 'SilanTutorial'
t1+s1 Output: TypeError: unsupported operand type(s) for +: 'int' and 'str'
