如下所示：
lists = ['tom','Jack','luCy','lily','jErry','anna']
dics = {'jack':'python','Lucy':'jaVa','jeRry':'rUby','lily':'c#',}
new_lists = []
for i in lists:
new_lists.append(i.lower())
print(new_lists)
new_dics = {}
for i,j in dics.items():
new_dics[i.lower()] = j.lower()
print(new_dics)
以上这篇python实现创建新列表和新字典,并使元素及键值对全部变成小写就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
