print()
list2 = ["china", "usa", "russian", "indian"]
# 方法2
# enmerate 是一个build in function 可以同时提供 index和item
for index, l1 in enumerate(list2):
    print(index + 1, l1, end="\t")

print()
#  方法3
for index in range(len(list1)):
    print(index + 1, list1[index], end='\t')

print()
# 方法4
[print(elements, end="\t") for elements in list1]

print()
# 方法5
i = 0
while i < len(list1):
    print(list1[i], end="\t")
    i = i + 1
