```
current_time_str = input("What is the current time (in hours 0-23)?")
wait_time_str = input("How many hours do you want to wait"

current_time_int = int(current_time_str)
wait_time_int = int(wait_time_str)

final_time_int = current_time_int + wait_time_int
print(final_time_int)
```
```
SyntaxError: bad input on line 4
```

The SyntaxError generated above is produced by the missing end parenthesis in line 2. This may be confusing because line 4 itself does not contain a syntax error. Since Python allows statements to continue over multiple lines inside parentheses, Python will continue to scan subsequent lines looking for the balanced right parenthesis. However in this case it finds the name`current_time_int` and it will want to interpret that as another parameter to the input function. But, there is not a comma to separate the previous string from the variable so as far as Python is concerned the error here is a missing comma on line 4.

SyntaxError Example

Syntax errors happen when you make an error in the syntax of your program. Syntax errors are like making grammatical errors in writing.

Usually SyntaxErrors can be traced back to missing punctuation characters, such as parentheses, quotation marks, or commas.

Many problems in your program will lead to an error message.

Most common error messages:
- SyntaxError
- TypeError
- NameError
- ValueError

Less common error messages:
- AttributeError
- TimeLimitError
- IndexError
- IndentationError
- ExternalError
- UnboundLocalError
- ImportError
- ZeroDivisionError
- KeyError
- IOError

SyntaxError

TypeErrors occur when you try to combine two objects that are not compatible. For example you try to add together an integer and a string. Usually type errors can be isolated to lines that are using mathematical operators, and usually the line number given by the error message is an accurate indication of the line.

TypeError

Name errors almost always mean that you have used a variable before it has a value. Often NameErrors are simply caused by typos in your code. Other times you may simply mis-remember the name of a variable or even a function you want to call.

NameError

Value errors occur when you pass a parameter to a function and the function is expecting a certain limitations on the values, and the value passed is not compatible.
