What is the problem with this code? "Invalid syntax" but why? And how to fix it Thx

Question

# Read an integer:
# a = int(input())
# Print a value:
# print(a)
a = input("type in the number")
na = a + 1
pa = a - 1
print ("The next number from the number "+a+ "is "+na+". ")
print ("The previous number from the number "+a+ "is "+pa+". ")

Answer 1

You can't add int to string.

In your code, first make sure you read the input as int

a = int(input("enter your number:"))

Second in the print statment convert the int to string, as to concatenate the strings.

print("some text " + str(a) + ".")

Or just use comma instead of plus, and print make the conversion for you.

print("some text", a, ".")

Answer 2

The syntax error is because you don't close the parentheses in print
