Why do I keep getting SyntaxError: invalid syntax in line 2?

Question

Here is my code:
x=4
If x==5:
Print("hello")
elif: x==7:
Print("greeting")
elif: x==4:
print("HI")

Answer 1

x=4
if x==5:
Print("hello")
elif x==7:
Print("greeting")
elif x==4:
print("HI")

identations are very important in python
also there were obsolete ':' just after the elif statements
and the first if was with a capital I
