写一个 Python 程序，用一个实例来检查字符是字母还是数字。
Python 程序检查字符是字母还是数字
这个 python 程序允许用户输入任何字符。接下来，我们使用 Elif 语句来检查用户给定的字符是字母还是数字。
- 这里 If 语句检查字符是在 A 和 Z 之间还是在 A 和 Z 之间，如果是 TRUE，则是字母表。否则，它进入 elif 语句。
- 在 Elif 语句中，我们正在检查给定的字符是否在 0 到 9 之间。如果是真的，就是一个数字；否则，它不是数字或字母。
# Python Program to check character is Alphabet or Digit
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")
elif(ch >= '0' and ch <= '9'):
print("The Given Character ", ch, "is a Digit")
else:
print("The Given Character ", ch, "is Not an Alphabet or a Digit")Python 字符是字母或数字输出
Please Enter Your Own Character : j
The Given Character j is an Alphabet
>>>
Please Enter Your Own Character : 6
The Given Character 6 is a Digit
>>>
Please Enter Your Own Character : .
The Given Character . is Not an Alphabet or a Digit使用 ASCII 值验证字符是字母还是数字的 Python 程序
在这个 Python 代码中，我们使用 ASCII 值来检查字符是字母还是数字。
# Python Program to check character is Alphabet or Digit
ch = input("Please Enter Your Own Character : ")
if(ord(ch) >= 48 and ord(ch) <= 57):
print("The Given Character ", ch, "is a Digit")
elif((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 or a Digit")Please Enter Your Own Character : q
The Given Character q is an Alphabet
>>>
Please Enter Your Own Character : ?
The Given Character ? is Not an Alphabet or a Digit
>>>
Please Enter Your Own Character : 6
The Given Character 6 is a DigitPython 程序使用 isalpha，isdigit 函数查找字符是字母还是数字
在这个例子 python 代码中，我们使用名为 isdigit 和 isalpha 的字符串函数来检查给定的字符是字母还是数字。
# Python Program to check character is Alphabet or Digit
ch = input("Please Enter Your Own Character : ")
if(ch.isdigit()):
print("The Given Character ", ch, "is a Digit")
elif(ch.isalpha()):
print("The Given Character ", ch, "is an Alphabet")
else:
print("The Given Character ", ch, "is Not an Alphabet or a Digit")原创文章，作者：O4OVT，如若转载，请注明出处：https://www.506064.com/n/127892.html
