1. 使用`len`函数和`rstrip`函数:
```python
file_name = '白夜行.txt'
try:
with open(file_name, encoding='utf8') as file_obj:
contents = file_obj.read()
words = contents.rstrip()
num_words = len(words)
print(f'The file {file_name} has about {num_words} words.')
except FileNotFoundError:
print(f'Sorry, the file {file_name} does not exist.')
2. 使用`split`函数和`len`函数:
```python
from string import split
def countWords(s):
words = split(s)
return len(words)
filename = 'welcome.txt'
total_words = 0
with open(filename, 'r') as file:
for line in file:
total_words += countWords(line)
print(total_words)
```python
import string
def count_words(s, n):
s = s.lower()
s = s.replace(string.punctuation, ' ')
words = s.split()
counts = {}
for w in words:
counts[w] = counts.get(w, 0) + 1
items = sorted(counts.items(), key=lambda x: (-x, x))
return items[:n]
print(count_words('betty bought a bit of butter but the butter was bitter', 3))
4. 使用`tkinter`库和定时器来实时显示文本字数:
```python
import tkinter as tk
def getlen():
txt = tk_text.get(1.0, tk.END)
txt_len = len(txt) - 1 Subtract 1 to exclude the newline character
print(f'{txt_len}')
tk_main.after(10000, getlen) Update every 10 seconds
tk_main = tk.Tk()
tk_text = tk.Text(tk_main)
tk_text.pack()
getlen()
tk_main.mainloop()
以上方法可以帮助你在Python中计算文本的字数。请选择适合你需求的方法进行操作
