items = [11, 22, 33, 44, 55, 66]
遍历数组
for item in items:
print(item)
遍历数组和下标
for i, item in enumerate(items):
print(i, item)
遍历字典keys
dicts = {"A": 1, "B": 2, "C": 3}
for dic in dicts:
print(dic)
for k in dicts.keys():
print(k)
遍历字典values
for v in dicts.values():
print(v)
遍历字典的key-value
for k, v in dicts.items():
print(k, v)
简化循环代码
result = []
for i in items:
result.append(i)
print(result)
result2 = [i + 1 for i in items]
print(result2)
result2 = map(lambda i: i + 1, items)
print(dict(result2))
