如果值在字符串中具有(dtd),(dnp),(不确定地),(针对整个季节)中的单词,我想将严重性列下的值替换为(1-4)级
我尝试使用字典进行替换,但它不会更改列下的元素
"time":"1600-12-31 18:46:16"
我正在清理2018-19赛季的NBA受伤数据

我将构建一个自定义函数,然后将其应用于字符串列:
def replace_severity(s):
"""matches string `s` for keys in `replace_dict` returning values from `replace_dict`"""
# define the keys + matches
replace_dict = {'DTD':1,'DNP':2,'out indefinitely':3,'out for season':4}
for key, value in replace_dict.items():
if re.search(key, s, re.I):
return value
# if no results
return None
# Apply this function to your column
df['Severity'] = df['Notes'].apply(replace_severity)
