In print function '+' is used for cascading likewise '<<' in c++ ...??

Question

my_mark = 55
print("My mark is " + my_mark ) it doesnt work

my_mark = 55
print("My mark is " + str(my_mark) ) it works

Answer 1

+ is for addition and you cant do calculation between str and int. you could use
print("my mark is ", my_mark) to print two different datatypes
