what is the purpose of a try block in python
to handle an error withour the program crashing
to try a math operation to see if the result is large or small
to try to get input to see if the progeam is being used
to try to print somthing to see if a printer is available
The purpose of a try block in Python is to handle errors that may occur during the execution of a program without causing the program to crash. In a try block, you can place code that may potentially raise an exception, and use except blocks to catch and handle those exceptions gracefully. This allows you to handle errors effectively and continue running the program even if unexpected errors occur.
which of the following lines does NOT contain a logic error
var <= 100
var < 100
var == 100
car > 100
The line "car > 100" contains a logic error. This is because "car" is not a recognized variable, and the comparison operator ">" is being used instead of "<" or "==" as seen in the other lines. This would result in a NameError when executed.
which of the following lines does NOT contain a logic error
var <= 100
var < 100
var == 100
var > 100
The line "var <= 100" does NOT contain a logic error. It is a valid comparison that checks if the variable "var" is less than or equal to 100. The other lines are also logically correct, but the choice "var <= 100" does not contain a logic error.
which of these lines will not result in a syntax error?
print(10 "is the result.")
print(10, is the result.")
print(10, "is the result.)
print(10, "is the result.")
The line that will not result in a syntax error is:
print(10, "is the result.")
This is because it contains the appropriate syntax for a print statement in Python with both the numerical value and the string to be printed provided as arguments. The other lines contain errors such as missing commas or incorrect string formatting, which would result in syntax errors when executed.
Which of these lines will not result in a syntax error
if 10 > 3
if 10 > 3:
of 10 > 3:
if 10 >< 3:
The line that will not result in a syntax error is:
if 10 > 3:
In Python, the correct syntax for an if statement includes a colon at the end of the condition. The line "if 10 > 3:" meets this requirement.
The other lines contain syntax errors:
- "if 10 > 3" is incomplete and lacks a colon at the end.
- "of 10 > 3:" contains a typo with "of" instead of "if".
- "if 10 >< 3:" uses an invalid comparison operator "><" which will result in a syntax error.
What error will occur if this is the first line of a program
a = b / 2
NameError
ZeroDivisionError
VariableError
TypeError
