使用通配符键匹配遍历字典 [英] Iterating over dictionary with wildcard key matching

问题描述

我正在尝试遍历字典以检索与键的模式 npi[0-9]+ 匹配的所有值.这在 Python 中可行吗?

I am trying to iterate over a dictionary in order to retrieve all values that match the pattern npi[0-9]+ for the key. Is this possible in Python?

for data in input_file:
    print(data['npi0'])
    print(data['npi1'])
    ....

推荐答案

您只需遍历您的字典，并对键进行模式匹配.

You just iterate over your dictionary, and do a pattern match on the key.

for key in dict:
    if re.match(r'npi[0-9]+', key):
        print(dict[key])
