Static variables :

access qualifier are known as static var. variable as static inside a function is declared than, the scope is less to the function, but it will exists for the life time of the program. Values will be persisted between successive calls to a function.

 #include<stdio.h> 
int fun() 
{ 
static int count = 0; 
 count++; 
 return count; 
} 
int main() 
{ 
 printf("%d ", fun()); 
 printf("%d ", fun()); 
return 0; 
}

in python it does not require for static keywords. inside this classs the method having instant var.

class CSStudent: 
    stream = 'cse'                  // Class Variable
    def __init__(self,name,roll):
        self.name = name            // Instance Variable
        self.roll = roll           
// Objects of CSStudent class
a = CSStudent('Prakash', 1)
b = CSStudent('Nidhi', 2)
print(a.stream)  
print(b.stream)
print(a.name)    
print(b.name)   
print(a.roll)    
print(b.roll)   
print(CSStudent.stream)
