StringContainsQ
StringContainsQ["string",patt]
StringContainsQ["string",{patt1,patt2,…}]
如果任一子字符串与任一 patti 匹配，则给出 True.
StringContainsQ[{"string1","string2",…},patt]
对每一个 "stringi" 给出结果.
StringContainsQ[patt]
表示可应用于表达式的 StringContainsQ 的算符形式.
更多信息和选项
- 串表达式 patt 可以包含 StringExpression 注释所指定的任意对象.
- StringContainsQ 接受以下选项：
-
IgnoreCase False 匹配时是否忽略大小写 - 设置选项 IgnoreCase->True 使 StringContainsQ 同等对待大小写字母.
- StringContainsQ[patt][expr] 等价于 StringContainsQ[expr,patt].
- StringConstainsQ[BioSequence["type","seq"],patt] 根据 patt 查找字符串 "seq". 在这种情况下，patt 中的简并字母被解释为基于生物分子序列类型的通配符模式. 使用 Verbatim["patt"] 从字面上匹配简并字母.
- BioSequence 的文档列出了每种类型的生物分子序列支持的简并字母.
- 如果 StringContainsQ 运算的生物分子序列是环状的，则可以进行环绕匹配.

属性和关系 (9)
StringContainsQ 逐项作用于第一个参数中的列表的各个元素：
StringContainsQ[{"aba", "bcd", "cea"}, "a"]StringContainsQ["string",{patt1,patt2,…}] 等价于 StringContainsQ["string",Alternatives[patt1,patt2,…]]：
StringContainsQ["cad", {"a", "b"}]StringContainsQ["cad", "a" | "b"]StringFreeQ["string",patt] 等价于 !StringContainsQ["string",patt]：
StringFreeQ["commit", "co"]StringContainsQ["commit", "co"]用 StringMatchQ 检查整个字符串是否与模式匹配：
StringMatchQ["commit", "om" ~~ __]StringContainsQ 检查子字符串是否与模式匹配：
StringContainsQ["commit", "om" ~~ __]当 StringMatchQ 为 True 时，StringContainsQ 通常返回 True：
StringMatchQ["commit", "co" ~~ __]StringContainsQ["commit", "co" ~~ __]StringContainsQ["string",patt] 等价于 StringMatchQ["string",___~~patt~~___]：
StringContainsQ["commit", "om"]StringMatchQ["commit", ___ ~~ "om" ~~ ___]StringStartsQ["string",patt] 等价于 StringContainsQ["string",StartOfString~~patt]：
