What's the problem with line 5 of my code?

Question

import random
a = random.randint (0,9)
print ("Your suitcase is locked with a 4-digit lock. It wouldn't be a problem if you hadn't forgot the combination. So, you have to guess the numbers one by one. From 0 to 9.")
b = int(input("Guess the first number:")
if b == a:
print ("You did it. The number is " + b)
elif b > a:
print ("The number is smaller.")
else:
print ("The number is bigger")

The code is in Python.

Answer 1

A closing parentheses was missing at the line where you read value for variable <b>

b = int(input("Guess the first number")) # <-- this line

Answer 2

The elif and else are indented one level too many – They need to be matched with the if

Answer 3

You cannot add a string and an integer.
You should first convert your integer to a string:

print(“You did it. The number is “ + str(b))

Answer 4

You're right. That was the problem. Thnx.
Now I have to write the rest of the code.

Answer 5

In if b == a's print statenent you should use str(b) to avoid TypeError (cannot concatenate integer to string)

Answer 6

I tried. Nothing happened. It always points to the colon on the end of line 5
if b === a:

Answer 7

Bug

Answer 8

On line 5, there is a missing closing parenthesis.

Correct code: b = int(input("Guess the first number."))
