Python 程序：統計字符串中元音和輔音

寫一個 Python 程序，使用 For 循環和 ASCII 值計算字符串中的元音和輔音，並給出一個實際例子。

計算字符串中元音和輔音的 Python 程序示例 1

這個 python 程序允許用戶輸入一個字符串。接下來，它使用 For 循環計算該字符串中元音和輔音的總數。首先，我們使用 Python For 循環來迭代字符串中的每個字符。在 For Loop 中，我們使用 If 語句檢查字符串字符是否為 A、E、I、O、u、A、E、I、O、u，如果為真，則增加元音值，否則增加輔音值

# Python Program to Count Vowels and Consonants in a String

str1 = input("Please Enter Your Own String : ")
vowels = 0
consonants = 0

for i in str1:
    if(i == 'a' or i == 'e' or i == 'i' or i == 'o' or i == 'u'
       or i == 'A' or i == 'E' or i == 'I' or i == 'O' or i == 'U'):
        vowels = vowels + 1
    else:
        consonants = consonants + 1

print("Total Number of Vowels in this String = ", vowels)
print("Total Number of Consonants in this String = ", consonants)

Python 計算字符串輸出中的元音和輔音

Please Enter Your Own String : Hello WOrld
Total Number of Vowels in this String =  3
Total Number of Consonants in this String =  8
>>> 
Please Enter Your Own String : Python Programs
Total Number of Vowels in this String =  3
Total Number of Consonants in this String =  12

計算字符串中元音和輔音的程序示例 2

在這個程序中，我們使用降低功能將字符串覆蓋為小寫。這樣，您只能在 Python If 語句中使用 a、e、I、o、u(避免大寫字母)。

# Python Program to Count Vowels and Consonants in a String

str1 = input("Please Enter Your Own String : ")
vowels = 0
consonants = 0
str1.lower()

for i in str1:
    if(i == 'a' or i == 'e' or i == 'i' or i == 'o' or i == 'u'):
        vowels = vowels + 1
    else:
        consonants = consonants + 1

print("Total Number of Vowels in this String = ", vowels)
print("Total Number of Consonants in this String = ", consonants)

計算元音和輔音總數的 Python 程序示例 3

這個程序使用 ASCII 值來查找元音和輔音。建議大家參考 ASCII 表文章了解 ASCII 值。

# Python Program to Count Vowels and Consonants in a String

str1 = input("Please Enter Your Own String : ")
vowels = 0
consonants = 0
str1.lower()

for i in str1:
    if(ord(i) == 65 or ord(i) == 69 or ord(i) == 73
       or ord(i) == 79 or ord(i) == 85
       or ord(i) == 97 or ord(i) == 101 or ord(i) == 105
       or ord(i) == 111 or ord(i) == 117):
        vowels = vowels + 1
    elif((ord(i) >= 97 and ord(i) <= 122) or (ord(i) >= 65 and ord(i) <= 90)):
        consonants = consonants + 1

print("Total Number of Vowels in this String = ", vowels)
print("Total Number of Consonants in this String = ", consonants)
