For those that are, identify the conclusion. For those that are not, determine the kind of nonargument. If someone avoids and is afraid of everything, standing firm against nothing, he becomes cowardly; if he is afraid of nothing at all and goes to face everything, he becomes rash. Similarly, if he gratifies himself with every pleasure and abstains from none, he becomes intemperate; if he avoids them all, he becomes some sort of insensible person. Temperance and bravery, then, are ruined by excess and deficiency, but preserved by the mean.

DefinitionIn this articleOverloads
Contains(Char)Returns a value indicating whether a specified character occurs within this string. public: bool Contains(char value);public bool Contains (char value);member this.Contains : char -> boolPublic Function Contains (value As Char) As BooleanParametersvalue Char The character to seek. ReturnsBooleantrue if the value parameter occurs within this string; otherwise, false. RemarksThis method performs an ordinal (case-sensitive and culture-insensitive) comparison. Applies toContains(String)Returns a value indicating whether a specified substring occurs within this string. public: bool Contains(System::String ^ value);public bool Contains (string value);member this.Contains : string -> boolPublic Function Contains (value As String) As BooleanParametersvalue String The string to seek. ReturnsBooleantrue if the value parameter occurs within this string, or if value is the empty string (""); otherwise, false. ExceptionsExamplesThe following example determines whether the string "fox" is a substring of a familiar quotation. If "fox" is found in the string, it also displays its starting position. using namespace System; int main() { String^ s1 = "The quick brown fox jumps over the lazy dog"; String^ s2 = "fox"; bool b = s1->Contains( s2 ); Console::WriteLine( "Is the string, s2, in the string, s1?: {0}", b ); if (b) { int index = s1->IndexOf(s2); if (index >= 0) Console::WriteLine("'{0} begins at character position {1}", s2, index + 1); } } // This example displays the following output: // 'fox' is in the string 'The quick brown fox jumps over the lazy dog': True // 'fox begins at character position 17 string s1 = "The quick brown fox jumps over the lazy dog"; string s2 = "fox"; bool b = s1.Contains(s2); Console.WriteLine("'{0}' is in the string '{1}': {2}", s2, s1, b); if (b) { int index = s1.IndexOf(s2); if (index >= 0) Console.WriteLine("'{0} begins at character position {1}", s2, index + 1); } // This example displays the following output: // 'fox' is in the string 'The quick brown fox jumps over the lazy dog': True // 'fox begins at character position 17 let s1 = "The quick brown fox jumps over the lazy dog" let s2 = "fox" let b = s1.Contains s2 printfn $"'{s2}' is in the string '{s1}': {b}" if b then let index = s1.IndexOf s2 if index >= 0 then printfn $"'{s2} begins at character position {index + 1}" // This example displays the following output: // 'fox' is in the string 'The quick brown fox jumps over the lazy dog': True // 'fox begins at character position 17 Class Example Public Shared Sub Main() Dim s1 As String = "The quick brown fox jumps over the lazy dog" Dim s2 As String = "fox" Dim b As Boolean = s1.Contains(s2) Console.WriteLine("'{0}' is in the string '{1}': {2}", s2, s1, b) If b Then Dim index As Integer = s1.IndexOf(s2) If index >= 0 Then Console.WriteLine("'{0} begins at character position {1}", s2, index + 1) End If End If End Sub End Class ' ' This example displays the following output: ' 'fox' is in the string 'The quick brown fox jumps over the lazy dog': True ' 'fox begins at character position 17RemarksThis method performs an ordinal (case-sensitive and culture-insensitive) comparison. The search begins at the first character position of this string and continues through the last character position. To perform a culture-sensitive or ordinal case-insensitive comparison:
If you are interested in the position of the substring value in the current instance, you can call the IndexOf method to get the starting position of its first occurrence, or you can call the LastIndexOf method to get the starting position of its last occurrence. The example includes a call to the IndexOf(String) method if a substring is found in a string instance. See also

Which method would you use to determine whether a certain substring is a suffix?Which method would you use to determine whether a certain substring is the suffix of a string? In slicing, if the end index specifies a position beyond the end of the string, Python will use the length of the string instead.
How do you find the substring of a string in Python?Python String find() method returns the lowest index or first occurrence of the substring if it is found in a given string. If it is not found, then it returns -1. Parameters: sub: Substring that needs to be searched in the given string.
How do you find out the part of the string from a string?To locate a substring in a string, use the indexOf() method. Let's say the following is our string. String str = "testdemo"; Find a substring 'demo' in a string and get the index.
