Python程序检查字符是否为字母

编写一个Python程序，通过实际示例检查字符是否为字母。

Python程序检查字符是否为字母

此Python程序允许用户输入任何字符。接下来，我们使用If Else语句检查用户输入的字符是否是字母。这里，If语句检查字符是否在a到z之间或A到Z之间。如果为TRUE，则它是一个字母；否则，它不是一个字母。

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

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

检查字符是否为字母的输出。

Please Enter Your Own Character : q
The Given Character  q is an Alphabet
>>> 
Please Enter Your Own Character : 8
The Given Character  8 is Not an Alphabet

Python程序使用ASCII值验证字符是否为字母

在此代码中，我们在If Else语句中使用ASCII值来检查字符是否为字母。有关更多信息，请参阅Python页面。

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

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

Please Enter Your Own Character : W
The Given Character  W is an Alphabet
>>> 
Please Enter Your Own Character : #
The Given Character  # is Not an Alphabet

Python程序使用isalpha函数查找字符是否为字母

在此示例代码中，我们使用isalpha字符串函数来检查给定字符是否为字母。

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

if(ch.isalpha()):
    print("The Given Character ", ch, "is an Alphabet")
else:
    print("The Given Character ", ch, "is Not an Alphabet")
