What is the correct structure to create a dictionary of months where each month will be accessed by its month number [for example, January is month 1, April is month 4]?
{ 1, 2,... 12 : 'January', 'February',... 'December' }
{ 1 ; 'January', 2 ; 'February', ... 12 ; 'December'}
{ 1 : 'January', 2 : 'February', ... 12 : 'December' }
[ '1' : 'January', '2' : 'February', ... '12' : 'December' ]

Determine which of the following passages are arguments. 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.

Other Quizlet setsRelated questionsWhich method would you use to determine whether a certain substring is present in a string quizlet?
Which method would you use to determine whether a certain substring is present in a string? The strip[] method returns a copy of the string with all the leading whitespace characters removed but does not remove trailing whitespace characters.
Which of the following string methods can be used to determine if a string contains only \n?
Which of the following string methods can be used to determine if a string contains only '\n' characters? The right side of the '*' must be an integer.
Which method could be used to remove specific characters from the end of a string?
Using 'str. replace[] , we can replace a specific character. If we want to remove that specific character, replace that character with an empty string. The str. replace[] method will replace all occurrences of the specific character mentioned.
What is the return value of the string method Lstrip []? Quizlet?
What is the return value of the lstrip[] string method? Returns a copy of the string with all leading whitespace removed.

Examples
The 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 17Remarks
This 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:
On .NET Core 2.1 and later versions: Call the Contains[String, StringComparison] overload instead.
On .NET Framework: Create a custom method. The following example illustrates one such approach. It defines a String extension method that includes a StringComparison parameter and indicates whether a string contains a substring when using the specified form of string 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.
