Question

我的CSV文件读为'keywords'，内容为： -

days    1
day     1
year    365
years   365
month   30
months  30
weeks   7
week    7

我正在将其作为列表阅读。

我有另一个包含内容的CSV文件： -

for thirty working days
for 30 working weeks
upto 40 months
till 5 weeks
for a period of 30 years
for a period of 30.36 days
for 30working
21 to 30#@ period days
30#@ period weeks
for a period of 30-36 weeks
3 weeks after sixty

我有一个函数（split_line），它会将'30'转换为'30'并将字符串赋回变量'WordasNumber' ..

我正在做的是查找从WordasNumber读取的字符串内容中是否有'days' or 'weeks' or 'months' or 'years' ...

如果有day，那么将该字符串中的数字乘以1 ...如果有week，则将字符串中的数字乘以7 ...就像明智乘以365 { {1}}和year

为30

我的代码

month

但我得到的输出是： -

import csv
import re
from word2number import w2n

with open("test_term.csv", "rb") as file1:
        reader = csv.reader(file1)
        extractedlist = list(reader)

def split_line(text):
    words = text.split(' ')
    number = 0
    #print words
    # for each word in the line:
    new_list = []
    for word in words:
        #print word
        #print w2n.word_to_num(word)
        conversion = w2n.word_to_num(word)
        if isinstance(conversion, (int,long)):
            #print conversion
            new_list.append(conversion)
            number = conversion            

        else:
            if word.isdigit():
                number = word
            new_list.append(word)


    return new_list, number
numbersProcessed = []
for extraRow in extractedlist:
    pnO = extraRow[0]
    extraRow[1] = re.sub(r'[^\w\s]', '', extraRow[1])
    if pnO in numbersProcessed:
        continue
    WordasNumber, number = split_line(extraRow[1])
    with open("dict.csv") as rawFile:
        reader = csv.reader(rawFile)
        keywords = list(reader)
        #print number
        #WordasNumber = re.match(r'[0-9]{3,}',WordasNumber).group()
    for a in WordasNumber:
        for line in keywords:
            #print line
            if(a==line[0]):
                value = line[1]
                #print value
                #print number
                try:

                    result = int(number)*int(value)
                    print pnO, ":" ,result
                    numbersProcessed.append(pnO)
                except:
                    pass

我看到，对于最后一个字符串，30 30303030303030 404040404040404040404040404040404040404040404040404040404040 5555555 3030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030303030 0 21 0 0 420转换为sixty并与60相乘，并输出7 ...但为什么是其他字符串条目连接而不是乘法？

420假设与30相乘得到连续365次...不确定我哪里出错......帮助！

注意： - 忽略输出中的0，因为我理解它，因为数字和跟随它的字符串之间没有空间......但是如果你有一个快速解决方案来解决它，那么欢迎!! < / p>

Answer 1

那是因为30是一个字符串，你不小心激活了字符串乘法。

"30" * 3 = "303030"

您需要在乘法之前将值转换为整数。

从源代码中修复它：在split_line中，而不是执行此操作：

if word.isdigit():
    number = word

DO

if word.isdigit():
    number = int(word)

'*'运算符正在缩写而不是乘法 - Python
