蟒蛇檢查是否字的文字部分字符串

Question

我想寫，檢查信件是否是一個字的一部分，例如

"u" part of word in "i c u" = false 
"u" part of word in "umbrella" = true 

Answer 1

>>> text = "i c u" 
>>> letter = "u" 
>>> any(letter in word and len(word) > 1 for word in text.split()) 
False 
>>> text = "umbrella" 
>>> any(letter in word and len(word) > 1 for word in text.split()) 
True 

你可以，如果你的情況下根據變化letter in word到letter.lower() in word.lower()功能敏感或nt。

Answer 2

假設你的意思是「一個字」是「對任何一方認爲是一個‘單詞字符’至少一個字符」，這會工作：

import re 
def letter_in_a_word(letter, words): 
    return bool(re.search(ur'\w{0}|{0}\w'.format(letter), words)) 

letter_in_a_word('u', 'i c u') # False 
letter_in_a_word('u', 'umbrella') # True 
letter_in_a_word('u', 'jump') # True 

Answer 3

>>> word = 'i c u' 
>>> letter = 'u' 
>>> letter in word.split(' ') 
True 
>>> word = 'umbrella' 
>>> letter in word.split(' ') 
False
