A programmer is writing a program in Python to determine a runner's performance level. The program should input a runner's finishing time in minutes. If the time is less than 45 minutes, it should output "Gold standard". Otherwise, it should output "Silver standard".
The current attempt contains three errors:
race_time = input("Enter your race time in minutes: ")
if race_time < 45
print("Gold standard")
else:
print("Silver standard"
Amend the program by writing the fully corrected code.
