Python 程序：檢查字符是小寫還是大寫

寫一個 Python 程序，通過一個實例，使用 islower 和 isupper 檢查字符是小寫還是大寫。

使用 islower 和 isupper 函數檢查字符是小寫還是大寫的 Python 程序

在這個 Python 示例中，我們使用 islower 和 isupper 字符串函數來檢查給定字符是小寫還是大寫。

# Python Program to check character is Lowercase or Uppercase
ch = input("Please Enter Your Own Character : ")

if(ch.isupper()):
    print("The Given Character ", ch, "is an Uppercase Alphabet")
elif(ch.islower()):
    print("The Given Character ", ch, "is a Lowercase Alphabet")
else:
    print("The Given Character ", ch, "is Not a Lower or Uppercase Alphabet")

檢查字符是否小寫的 Python 程序

這個 python 程序允許用戶輸入任何字符。接下來，我們使用 Elif 語句來檢查用戶給定的字符是小寫還是大寫。

• 這裡 If 語句檢查字符是否大於等於小 a，小於等於 z，如果是 TRUE，則為大寫。否則，它進入 elif 語句。
• 在 Elif 中，我們檢查給定的字符是否大於或等於 A，小於或等於 z。如果為真，則它是小寫字符。否則，它不是小寫字母或大寫字母。

# Python Program to check character is Lowercase or Uppercase
ch = input("Please Enter Your Own Character : ")

if(ch >= 'A' and ch <= 'Z'):
    print("The Given Character ", ch, "is an Uppercase Alphabet") 
elif(ch >= 'a' and ch <= 'z'):
    print("The Given Character ", ch, "is a Lowercase Alphabet")
else:
    print("The Given Character ", ch, "is Not a Lower or Uppercase Alphabet")

Python 字符是小寫還是大寫輸出

Please Enter Your Own Character : #
The Given Character  # is Not a Lower or Uppercase Alphabet
>>> 
Please Enter Your Own Character : T
The Given Character  T is an Uppercase Alphabet
>>> 
Please Enter Your Own Character : g
The Given Character  g is a Lowercase Alphabet

Python 程序使用 ASCII 值檢查字符是否為小寫

在這段 Python 代碼中，我們使用 ASCII 值來檢查字符是大寫還是小寫。

ch = input("Please Enter Your Own Character : ")

if(ord(ch) >= 65 and ord(ch) <= 90): 
    print("The Given Character ", ch, "is an Uppercase Alphabet") 
elif(ord(ch) >= 97 and ord(ch) <= 122):
    print("The Given Character ", ch, "is a Lowercase Alphabet")
else:
    print("The Given Character ", ch, "is Not a Lower or Uppercase Alphabet")

Please Enter Your Own Character : o
The Given Character  o is a Lowercase Alphabet
>>> 
Please Enter Your Own Character : R
The Given Character  R is an Uppercase Alphabet
>>> 
Please Enter Your Own Character : $
The Given Character  $ is Not a Lower or Uppercase Alphabet
