Python遍历列表的几种方法

for循环

list_test = [1, 3, 6, 2, 5]
for i in list_test:
print(i)

while循环

list_test = [1, 3, 6, 2, 5]
i = 0
while i < len(list_test):
print(list_test[i])
i += 1

enumerate函数

list_test = [1, 3, 6, 2, 5]
for index, value in enumerate(list_test):
print(index, value)

range函数

list_test = [1, 3, 6, 2, 5]
for i in range(len(list_test)):
print(i, list_test[i])
# range()函数返回的是一个可迭代对象，不是列表

iter函数

list_test = [1, 3, 6, 2, 5]
for i in iter(list_test):
print(i)
