# LOOP PAKAI RANGE
# range()
range(5) # 0,1,2,3,4
range(1,5) # 1,2,3,4
range(1,10,2) # 1,3,5,7,9



# WHILE LOOP
# menggunakan while dan :
i = 0
while i < 5:
  print(i)

# LOOPING DICT
# Looping keys (default)

# Looping values
for value in user.values():

# Looping key + value
for key, value in user.items():

# LOOPING WITH INDEX
for index, fruit in enumerate(fruits):
  print(index, fruit)


# BREAK & CONTINUE
# break
for n in range(10):
  if n == 5:
    break

# ELSE DI LOOP
# else berjalan jika loop tidak break
for i in range(5):
  print(i)

  print("Loop selesai")


# LOOP COMPEREHENSION
