[英]How to fix python not writing to file
我正在编写一个脚本,该脚本读取字典并挑选出符合搜索条件的单词。 该代码运行良好,但是问题是它没有将任何单词写入文件“哇”或将它们打印出来。 该词典的来源是https://github.com/dwyl/english-words/blob/master/words.zip 。
我尝试将文件的开头更改为“ w +”而不是“ a +”,但没有任何区别。 我检查了是否没有符合条件的单词,但这不是问题。
listExample = [] #creates a list
with open("words.txt") as f: #opens the "words" text file
for line in f:
listExample.append(line)
x = 0
file = open("wow.txt","a+") #opens "wow" so I can save the right words to it
while True:
if x < 5000: # limits the search because I don't want to wait too long
if len(listExample[x]) == 11: #this loop iterates through all words
word = listExample[x] #if the words is 11 letters long
lastLetter = word[10]
print(x)
if lastLetter == "t": #and the last letter is t
file.write(word) #it writes the word to the file "wow"
print("This word is cool!",word) #and prints it
else:
print(word) #or it just prints it
x += 1 #iteration
else:
file.close()
break #breaks after 5000 to keep it short
它创建了“哇”文件,但它是空的。 如何解决此问题?
这样可以解决您的问题。 您以这样一种方式拆分文本,即每个单词的末尾都有一个换行符,也可能有一个空格。 我已经放入.strip()
摆脱了任何空格。 另外,我已将lastLetter
定义为word[-1]
以获取最后一个字母,而不管单词的长度如何。
PS感谢Ocaso Protal建议剥离而不是更换。

else:
print('closing')
file.close()
break #breaks after 5000 to keep it short
