How can we know the body of while is end there is no bracket to tell us?

Answer 1

By looking at the levels of indentation.

Statements within the same block of code need to be indented at the same level.

for i in range(42):
while True:
print(i)
break
print(42) # Same level of indentation as the while loop

Answer 2

Something like this.

if n==0: # Level 0, no indentation
if n==1: # Level 1
if n==2: # Level 2
...
else: # Level 2
...
else: # Level 1
...
else: # Level 0
...
