可以使用Python的max()函数结合列表推导式来求最长单词的字母数。首先,我们可以将每个单词的长度作为列表的元素,然后使用max()函数找到列表中的最大值。
以下是示例代码:
```python
words = ['apple', 'pear', 'orange', 'pineapple', 'banana']
max_length = max(len(word) for word in words)
print("The length of the longest word is:", max_length)
```
输出结果为:
```
The length of the longest word is: 9
```

用Python写一个背单词系统
好的,以下是一个简单的背单词系统的Python代码示例:
```python
import random
# 单词列表
words = {
"apple": "苹果",
"banana": "香蕉",
"orange": "橙子",
"grape": "葡萄",
"watermelon": "西瓜",
"pear": "梨子",
"pineapple": "菠萝",
"peach": "桃子",
"lemon": "柠檬"
}
# 随机选择一个单词
word = random.choice(list(words.keys()))
# 提示用户翻译
print("请翻译单词:", word)
# 获取用户输入
answer = input()
# 判断答案是否正确
if answer == words[word]:
print("答案正确!")
else:
print("答案错误,正确答案是:", words[word])
```
这个程序会从一个单词列表中随机选择一个单词,然后提示用户翻译这个单词。用户输入答案后,程序会判断答案是否正确,并输出相应的提示信息。您可以根据需要对程序进行修改和扩展。
用python编写的测试英语单词的程序
Great! Here's a simple program that can help you test your English vocabulary.
```python
import random
# Define a list of words to be tested
words = ['apple', 'banana', 'cherry', 'orange', 'pear', 'grape', 'watermelon', 'pineapple', 'kiwi', 'mango']
# Set the number of questions to be asked
num_questions = 5
# Shuffle the list of words
random.shuffle(words)
# Loop through the shuffled list and ask questions
for i in range(num_questions):
word = words[i]
answer = input(f"What is the meaning of '{word}'? ")
# Check if the answer is correct and print the result
if answer.lower() == 'fruit':
print("Correct!")
else:
print("Incorrect!")
```
In this program, we first define a list of words to be tested. We then set the number of questions to be asked and shuffle the list of words using the `random.shuffle` function.
We then loop through the shuffled list and ask a question for each word using the `input` function. We check if the answer is correct (in this case, the correct answer is 'fruit') and print the result.
You can modify the program to include more words, change the number of questions, and even add more types of questions (e.g. asking for synonyms or antonyms).
