Question

我正在尝试创建一个逐个匹配用户输入的应用程序，并显示它所属的句子的百分比（预定义的句子）

store_word=""
def client_query_function():
    point =0 
    i=0
    z=0 #tells the index number of the sentence
    p=""
    global store_word
    client_query = raw_input(">> ")
    len_client_query=len(client_query)
    i=len_client_query
    for z in range(i):  
        #print client_query[z]
        if  client_query[z]!=" ":
                p=p+client_query[z]     
                store_word=""   
        else:
            store_word=p
            print "store_word" ,store_word

            #dictonary search

timeis =[]
dateis = []

client_query_function()

def timeis_funct(store_word):   
    global pm_timeis    
    timeis[5]=["what","is","the","time","?",""]
    for i in range (len(timeis)):
        if store_word==timeis[i]:
            pm_timeis=pm_timeis+1
        else:
            continue
    return pm_timeis

def dateis_funct(store_word):   
    global pm_dateis    
    dateis[5]=["what","is","the","date","?",""]
    for i in range (len(dateis)):
        if store_word==dateis[i]:
            pm_dateis=pm_dateis+1
        else:
            continue
    return pm_dateis


def percent_cal():
    timeis_funct(store_word)
    dateis_funct(store_word)
percent_cal()

在运行程序时，它显示列表分配索引超出范围，这不应该发生

Answer 1

timeis[5]=["what","is","the","time","?",""]

这不是使用五个元素创建名为timeis的列表的正确方法。左侧的索引是不必要的。尝试：

timeis=["what","is","the","time","?",""]

同样适用于dateis[5]=["what","is","the","date","?",""]。

此外，您将获得NameError: global name 'pm_timeis' is not defined，因为在函数内部使用之前，您从未使用该名称声明变量。如果global语句不存在，则pm_timeis=0 pm_dateis=0语句不会创建该变量;你仍然需要自己做。您需要添加

timeis_funct

在致电dateis_funct和public class Eshop implements java.io.Serializable { /** * */ private static final long serialVersionUID = 1L; public Eshop() {} public Eshop(int eshopId, String code, String name, String lastModified) { this.eshopId = eshopId; this.code = code; this.name = name; this.lastModified = lastModified; } public int eshopId; public String code; public String name; public String lastModified; public int getEshopId() { return eshopId; } public void setEshopId(int eshopId) { eshopId = eshopId; } public String getCode() { return code; } public void setCode(String code) { code = code; } public String getName() { return name; } public void setName(String name) { name = name; } public String getLastModified() { return lastModified; } public void setLastModified(String lastModified) { lastModified = lastModified; }之前，代码中的某处。

索引错误：列表分配索引超出范围
