【问题描述】:
我试图编写一个从随机文本文件中选择单词的单词计数器程序。条件是重复 5 次或更多的单词将被写在屏幕上。我尝试了很多例子。我用这样的 if 条件尝试了 count() 函数:
如果 fullText.count(word) > 5:...
但它不起作用。
这是我的代码:
from tkinter import *
from tkinter import filedialog
main = Tk()
main.title(".TXT File Word Counter")
main.resizable(height=FALSE, width=FALSE)
main.geometry('500x400')
main.configure(bg='#757575')
labelfont = ("Arial", 14, "bold")
result = dict()
def clear_text():
textfield.delete(0, END)
ShowCountedWords.delete(1.0, END)
def open_file():
main.filename = filedialog.askopenfilename()
def count_word(file):
fileOpen = open(str(file), 'r')
fullText = fileOpen.readlines()
fileOpen.close()
for word in textfield.get().split(', '):
for text in fullText:
if word in result:
result[word] = result[word] + text.count(word)
else:
result[word] = text.count(word)
ShowCountedWords.delete(1.0, END)
for key, value in result.items():
ShowCountedWords.insert('1.0', '{0} : {1} \n'.format(key, value))
result.clear()
heading = Label(main, text=".TXT File Word Counter")
heading.place(x=150, y=2)
heading.config(bg="#757575", font=labelfont, fg="#ffffff")
textfield = Entry()
textfield.place(x=3, y=30)
textfield.config(width=81, borderwidth=2)
btnSelectFile = Button(main, text="Select .txt File", command=lambda : open_file())
btnSelectFile.place(x=4, y=60)
btnSelectFile.config(width=20, bg="#66BB6A")
btnCount = Button(main, text="Count Words", command=lambda : count_word(main.filename))
btnCount.place(x=173, y=60)
btnCount.config(width=20, bg="#42A5F5")
btnClear = Button(main, text="Clear", command=lambda : clear_text())
btnClear.place(x=344, y=60)
btnClear.config(width=20, bg="#ef5350")
ShowCountedWords = Text(main, height=18, width=61)
ShowCountedWords.place(x=4, y=100)
ShowCountedWords.config(bg="#616161", fg="#ffffff")
main.mainloop()
我该怎么办? (tkinter 在这个问题上并不重要。)
【问题讨论】:
-
您可以逐字逐句将每个新单词添加到字典中,其中键是单词,值是它出现的次数,然后遍历字典并仅打印值的键等于 5
-
@SH 描述的是一个很好的策略,并且有一个内置的类
collections.Counter来实现它。
