What is an easy way in Golang to check if all characters in a string are upper case or lower case?
Also, how to handle a case where the string has punctuation?
See these examples:
package mainimport ( "fmt" "unicode")func main() { s := "UPPERCASE" fmt.Println(s.IsUpper()) // Should print true s = "lowercase" fmt.Println(s.IsUpper()) // Should print false s = "lowercase" fmt.Println(s.IsLower()) // Should print true s = "I'M YELLING AT YOU!" fmt.Println(s.IsUpper()) // Should print true}
Note: s.IsUpper() and s.IsLower() doesn't really exist, but would be nice to find an equivalent.
How can I convert all values in an array to lowercase in PHP?
Something like array_change_key_case
?
I am new in regular expression. I want to remove a uppercase letter if it has lowercase before and after it. If the input is "I wilYl go theXre"
then the output should be "I will go there"
. How can I get it?
This question already has an answer here:
I am not sure of best way to convert all Strings in a collection to lowercase. Any thoughts?
private Set<String> email; if(userEmail instanceof Collection) { this.email = new HashSet<String>((Collection<String>) userEmail); model.put("userEmail", this.email); //need to convert this to lower case}
Thanks in advance :-)
I have a dataframe like the one displayed below:
# Create an example dataframe about a fictional armyraw_data = {'regiment': ['Nighthawks', 'Nighthawks', 'Nighthawks', 'Nighthawks'], 'company': ['1st', '1st', '2nd', '2nd'], 'deaths': ['kkk', 52, '25', 616], 'battles': [5, '42', 2, 2], 'size': ['l', 'll', 'l', 'm']}df = pd.DataFrame(raw_data, columns = ['regiment', 'company', 'deaths', 'battles', 'size'])
My goal is to transform every single string inside of the dataframe to upper case so that it looks like this:
Notice: all data types are objects and must not be changed; the output must contain all objects. I want to avoid to convert every single column one by one... I would like to do it generally over the whole dataframe possibly.
What I tried so far is to do this but without success
df.str.upper()
