Python如何通过指定字符获取字符串中的单词？

Question

a = "I only want the $1000"print(get_word_containing("$")output: $1000我如何通过该单词中的字符来获取字符串中的整个单词，如上所示？

Answer 1

您的函数可以简单如下：

def get_word_containing(string, char):

    words = [word for word in string.split() if char in word]

    return words

string = "I only want the $1000"

print(get_word_containing(string, "$"))

输出：

['$1000']

Answer 2

我将稍微修改 @Biplob 函数来打印字符串：

def get_word_containing(myStr, char):

    for x in myStr.split():

      if char in x:

        print(x)

mystring = "I only want the $1000"

get_word_containing(mystring, "$")

Answer 3

import re

a = "I only want the $1000"

list = re.findall("[$]\w+", text)

print(list)

上面的代码将为您提供字符串中以 $ 开头的所有单词的数组

Answer 4

import re

def get_word_containing(myStr, char):

    list = re.findall("["+char+"]\w+", myStr)

    return list;

mystring = "I only $200 want the $1000"

ouput = get_word_containing(mystring, "$")

print(ouput);

所以它会给我们 ['$200', '$1000']
