·各项数值符合要求的角色

【火/冰/……属性的角色】

from pandas import DataFrame, Series
import pandas as pd
import numpy as np
Attribute = "火"
role_things = pd.read_excel("C:/Users/YHT/Desktop/项目/原神各属性角色信息.xlsx", header=0, index_col=0)
role_things = role_things.fillna(axis=0, method="ffill")
num = 0
n = 0
All = []
for x in role_things["属性"]:
    if x == Attribute:
        All.append(num)
        n += 1
    num += 1
print(All)
All_role = role_things.iloc[All]
print(All_role)

【查找某个角色的数值】

from pandas import DataFrame, Series
import pandas as pd
import numpy as np

role_name = "班尼特"
role_things = pd.read_excel("C:/Users/YHT/Desktop/项目/原神各属性角色信息.xlsx", header=0, index_col=0)
# 将属性所包含的nan，进行填充
role_things = role_things.fillna(axis=0, method="ffill")
print(role_things)
print()
all_name = role_things["角色"]
print(all_name)
num = 0
for x in all_name:
    if x == role_name:
        return_role = role_things.loc[:, "角色":]
        print(return_role.iloc[num])
        Attribute = return_role.iloc[num]["属性"]
        Name = return_role.iloc[num]["角色"]
        Hp = return_role.iloc[num]["生命值"]
        Def = return_role.iloc[num]["防御力"]
        Atk = return_role.iloc[num]["攻击力"]
        Break = return_role.iloc[num]["突破加成"]
        print(Name, Attribute, Hp, Def, Atk, Break)
    num += 1

【各项数值符合要求的角色】
