- Convert whole dataframe from lower case to upper case with Pandas
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() - Converting Odd and Even-indexed characters in a string to uppercase/lowercase in Javascript?
I need to make a function that reads a string input and converts the odd indexed characters in the string to upperCase and the even ones to lowerCase.
function alternativeCase(string){ for(var i = 0; i < string.length; i++){ if (i % 2 != 0) { string[i].toUpperCase(); } else { string[i].toLowerCase(); } } return string;}How to fix my code?
- Flask-sqlalchemy does not convert tablenames to lowercase (mysql)
I am trying to create tables in mysql with flask-sqlalchemy. My problem is that the classnames always start with capital letters while I would like to create all tables with lowercase.
Is there a way to fix that? I read that the default behaviour of the flask-sqlalchemy is converting it to lowercase, but it does not seem to work for me.
Thanks for any advice :)
- Using upper-case and lower-case xpath functions in selenium IDE
I am trying to get a xpath query using the xpath function
lower-caseorupper-case, but they seem to not work in selenium (where I test my xpath before I apply it).Example that does NOT work:
//*[.=upper-case('some text')]I have no problem locating the nodes I need in complex path and even using aggregated functions, as long as I don't use the upper and lower case.
Has anyone encountered this before? Does it make sense?
Thanks.
- Is it bad to use uppercase letters for html tags?
What is the best practice?
<HTML> or <html>And why we should stick with one particular case?
However all browsers seems to interpret both cases and returns the expected output.
