Python 程序检查字符是否为数字

编写一个Python程序，通过实际示例检查字符是否为数字。

Python 程序检查字符是否为数字

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为数字。在这里，If语句检查字符是否大于或等于0，并且小于或等于9。如果为TRUE，则该字符是数字。否则，它不是数字。

# Python Program to check character is Digit or not
ch = input("Please Enter Your Own Character : ")

if(ch >= '0' and ch <= '9'):
    print("The Given Character ", ch, "is a Digit")
else:
    print("The Given Character ", ch, "is Not a Digit")

Python 字符是数字还是非数字的输出

Please Enter Your Own Character : 1
The Given Character  1 is a Digit
>>> 
Please Enter Your Own Character : i
The Given Character  i is Not a Digit

Python 程序使用 ASCII 值查找字符是否为数字

在此 Python 示例中，我们使用 ASCII 值来检查字符是否为数字。

# Python Program to check character is Digit or not
ch = input("Please Enter Your Own Character : ")

if(ord(ch) >= 48 and ord(ch) <= 57):
    print("The Given Character ", ch, "is a Digit")
else:
    print("The Given Character ", ch, "is Not a Digit")

Please Enter Your Own Character : 7
The Given Character  7 is a Digit
>>> 
Please Enter Your Own Character : @
The Given Character  @ is Not a Digit

Python 程序使用 isdigit 函数验证字符是否为数字

在此示例 Python 代码中，我们在 If Else 语句中使用 isdigit 字符串函数来检查给定字符是否为数字。

# Python Program to check character is Digit or not
ch = input("Please Enter Your Own Character : ")

if(ch.isdigit()):
    print("The Given Character ", ch, "is a Digit")
else:
    print("The Given Character ", ch, "is Not a Digit")
