@Python_Dv إسناد Today I learned this in my Python class # Step 1: assign the string "Hi " to variable a a = "Hi " # Step 2: multiply the string by 3 → repeats it 3 times # "Hi " * 3 = "Hi Hi Hi " # Step 3: concatenate with "Python" print(a * 3 + "Python") # Output: Hi Hi Hi Python

@Python_Dv A (Hi Hi Hi Python). a = 'Hi ' (note the space!). a * 3 repeats the string = 'Hi Hi Hi '. Then + 'Python' concatenates = 'Hi Hi Hi Python'. For beginners: * repeats strings, + joins them. Order matters: (a * 3) happens first, then + 'Python'.

@Python_Dv Error! string can't be multiply with integer.
@Python_Dv Small note: in Python the error message is not just "Error" but specifically "SyntaxError". So option D should be SyntaxError, not just Error.
@Python_Dv Explanation: 1. a = 'Hi' This assigns the string 'Hi' to the variable a. 2. a * 3 This repeats the string 'Hi' three times: 'Hi' * 3 → 'HiHiHi' '3. HiHiHi' + 'Python' This concatenates the two strings: 'HiHiHiPython' 4. Output is: HiHiHiPython Answer: B) HiHiHiPython
@Python_Dv A because * has a higher operator precedence and it is earlier in the expression.
@Python_Dv a = "Ho " print(a * 3 + "Merry Christmas")
@Python_Dv a = 'Hi ' → a contains Hi (with a space). a * 3 → repeats 'Hi ' three times → 'Hi Hi Hi '. 'Hi Hi Hi ' + 'Python' → concatenates the string → 'Hi Hi Hi Python'. Correct answer: A) Hi Hi Hi Python
