Question

我目前正在尝试计算用户输入的句子中的单词数量，并计算单词“ Python”在该句子中的使用次数，并在最后显示两个结果。我试图将句子强制转换为小写字母，但目前不确定如何将其集成到代码中。到目前为止，它计算的是输入“ Python”的次数，而不是“ python”的次数，我需要同时注册两者。

const rotation = this.state.iconRotated ? 90 : 0
<TouchableOpacity onPress={this.toggleExpanded}>
  <View style={{ alignItems: "center" }}>
  <Icon
    iconStyle={
      {
        paddingTop:"13%",
        paddingRight: 50,
        transform: `${rotate(rotation)}`
      }
    }
    name="play-circle"
    color="#637182"
    type="light"
    size={30}
  />
  </View>
</TouchableOpacity>

Answer 1

首先将整个输入句子转换为小写

sentence = input(str("Please enter a sentence with your thoughts on Python:"))
howManyPython = sentence.lower().count ("python")
listOfWords = len(sentence.split())
print("You said Python " + str(howManyPython) + " times!")
print("There was " + str(listOfWords), "words in your sentence")

# output
Please enter a sentence with your thoughts on Python:python 123 Python Python
You said Python 3 times!
There was 4 words in your sentence

Answer 2

您可以将整个输入字符串转换为小写字母，以计算单词“ Python”：

sentence = 'Python python python3000 py'
listOfWords = len(sentence.split())
howManyPython = sentence.lower().count("python")  # convert to lowercase
print("You said Python " + str(howManyPython) + " times!")
print("There was " + str(listOfWords) + " words in your sentence")

返回：

You said Python 3 times!
There was 4 words in your sentence
