抱歉，这段代码有很多错误，需要进行修改。以下是修改后的代码：

import pandas as pd
import numpy as np
from sklearn.cluster import KMeans
from sklearn.metrics import fowlkes_mallows_score

# 读取原始数据
user = pd.read_csv("APP.csv", encoding='gbk')

# 处理缺失值
user.fillna(0.0, inplace=True)

# 处理用户分享概率小于0的情况
user.loc[user["不愿分享概率"] < 0, "不愿分享概率"] = 0

# 处理用户分享概率大于1的情况
user.loc[user["不愿分享概率"] > 1, "不愿分享概率"] = 1

# 处理用户是否点击分享
user["是否点击分享"] = user["是香点击分享"].apply(lambda x: 1 if x == 'T' else 0)

# 用户编码
coding = {'a': 0, 'b': 1, 'c': 2, 'd': 3, 'e': 4, 'r': 12, 'k': 10, 'l': 11, 't': 19, 'u': 20, 'v': 21, 'x': 23, 'y': 24}
def tocode(s):
    code = 0
    for c in s.lower():
        if c in coding.keys():
            code = code * 26 + coding[c]
    return code
user["用户编码"] = user["用户名"].apply(lambda x: tocode(x))

# 分组后在线时长
user["分组后在线时长"] = pd.qcut(user["在线时长"], 4, labels=[4, 3, 2, 1])

# 保存处理后的数据
user_clean = user[["用户编码", "不愿分享概率", "愿意分享概率", "在线时长", "分组后在线时长", "是否点击分享"]]
user_clean.to_csv("user_clean.csv", index=False)

# 特征工程
user_feature = pd.read_csv("user_clean.csv")

# K-Means聚类
X = user_feature[["不愿分享概率", "愿意分享概率", "在线时长", "分组后在线时长"]]
y = user_feature["是否点击分享"]
model = KMeans(n_clusters=2).fit(X)
model.labels_ = list(model.labels_)
score = fowlkes_mallows_score(y, model.labels_)
print('FMI评价分值为：%f' % score)

这段代码的功能是对用户数据进行一系列处理和特征工程，最后使用KMeans算法进行聚类并输出FMI评价分值。
