Broken boot script
The flight computer on Python One runs a short boot script every time it powers on. Last night someone edited the script in a hurry, and now the computer won't start: Python refuses to run the file at all.
When a single quote or bracket is missing, Python can't make sense of the file, so not even the first line runs. That's a SyntaxError. Find what's missing and get the boot script running again.
Finish stage 1 to unlock this stage.
Run the boot script. Instead of booting, it stops with an error: one line is missing its closing quote. Fix it so the script prints:
Booting flight computer... Loading navigation data... Boot complete

The next part of the boot script checks the sensors, and it was edited in the same hurry: a closing bracket is missing. Run it, read the error and fix the line it names. The output must be:
Booting flight computer... Checking fuel sensors... OK Checking star tracker... OK Boot complete
Finish stage 2 to unlock this stage.
The last part arms the engines. This time two lines are broken: one has quotes that don't match, and another is missing a bracket. Python only reports the first problem it finds. Fix it, run again, and the next error shows up. Keep going until the script prints:
Booting flight computer... Arming engines... Engines armed Boot complete
Hints
First Program - Hello Space
# Your first Python program
print("Hello, Space!")
# Python reads your code from top to bottom
# Each print() displays one line of text
print("Mission Control online.")
print("All systems ready.")
# You can print numbers the same way
print(2077)
# Try changing the text inside the quotes
print("3... 2... 1...")
print("Liftoff!")
