Python | 字符串isdecimal(),isdigit(),isnumeric()和Methods之间的区别
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
The methods isdigit(), isnumeric() and isdecimal() are in-built methods of String in python programming language, which are worked with strings as Unicode objects. These functions return either true or false.
方法isdigit() , isnumeric()和isdecimal()是python編程語言中String的內置方法,可將字符串作為Unicode對象使用。 這些函數返回true或false 。
The comparison is based on Unicode classifications,
比較是基于Unicode分類,
| Example of string with decimal characters: "12345" "12" "98201" | Example of string with digits: "12345" "1233" "3" | Example of string with numerics: "12345" "??" "?" "12345?" |
| Returns ‘true’ if all characters of the string are decimal. | Returns ‘true’ if all characters of the string are digits. | Returns ‘true if all characters of the string are numeric. |

| 帶十進制字符的字符串示例: “ 12345” “ 12” “ 98201” | 帶數字的字符串示例: “ 12345” “ 123 3 ” “ 3 ” | 帶數字的字符串示例: “ 12345” “??” “?” “12345?” |
| 如果字符串的所有字符均為十進制,則返回“ true”。 | 如果字符串的所有字符都是數字,則返回“ true”。 | 如果字符串的所有字符均為數字,則返回'true。 |
| : 字符串isdecimal()方法 | : 字符串isdigit()方法 | : 字符串isnumeric()方法 |
Example:
例:
str1 = u"362436" #decimal characters str2 = u"3" #unicode digit str3 = u"??" #fractional valueprint "str1 :" print "str1.isdecimal () : ", str1.isdecimal () print "str1.isnumeric () : ", str1.isnumeric () print "str1.isdigit () : ", str1.isdigit ()print "str2 :" print "str2.isdecimal () : ", str2.isdecimal () print "str2.isnumeric () : ", str2.isnumeric () print "str2.isdigit () : ", str2.isdigit ()print "str3 :" print "str3.isdecimal () : ", str3.isdecimal () print "str3.isnumeric () : ", str3.isnumeric () print "str3.isdigit () : ", str3.isdigit ()Output
輸出量
str1 :str1.isdecimal () : Truestr1.isnumeric () : Truestr1.isdigit () : Truestr2 :str2.isdecimal () : Truestr2.isnumeric () : Truestr2.isdigit () : Truestr3 :str3.isdecimal () : Falsestr3.isnumeric () : Truestr3.isdigit () : False翻譯自: https://www.includehelp.com/python/difference-between-string-isdecimal-isdigit-isnumeric-and-methods.aspx
