Online Lower Case Converter

I need to know if there is a function that detects the lowercase letters in a string. Say I started writing this program:

s = input('Type a word')

Would there be a function that lets me detect a lowercase letter within the string s? Possibly ending up with assigning those letters to a different variable, or just printing the lowercase letters or number of lowercase letters.

While those would be what I would like to do with it I'm most interested in how to detect the presence of lowercase letters. The simplest methods would be welcome, I am only in an introductory python course so my teacher wouldn't want to see complex solutions when I take my midterm. Thanks for the help!

I am trying to run a query using Eloquentthe $vars['language'] is in lower case but the language column is not necessarily in lower case. How can i do this search using eloquent but still have the lower case in the query

Item::where('language', $vars['language'])

What i want to do is this even though i can't find anywhere how to do this

Item::where('LOWER(language)', $vars['language'])

so that they are both in lowercase and then i can get them to match.

I've just compiled the version MySQL 8.0.12 in a Ubuntu 16.0.4.

After following the instructions in the website and making the following my.cnf file:

[mysqld]datadir=/usr/local/mysql/datasocket=/tmp/mysql.sockport=3306log-error=/usr/local/mysql/data/localhost.localdomain.erruser=mysqlsecure_file_priv=/usr/local/mysql/mysql-fileslocal_infile=OFFlog_error = /var/log/mysql/error.log# Remove case sensitive in table nameslower_case_table_names=1

I get the following error:

2018-08-11T19:45:06.461585Z 1 [ERROR] [MY-011087] [Server] Different lower_case_table_names settings for server ('1') and data dictionary ('0').

What should I change so that data dictionary is aligned to server settings?

Is there a way to convert a string from uppercase, or even part uppercase to lowercase?

For example, "Kilometers" → "kilometers".

Is there a function built into Java that capitalizes the first character of each word in a String, and does not affect the others?

Examples:

• jon skeet -> Jon Skeet
• miles o'Brien -> Miles O'Brien (B remains capital, this rules out Title Case)
• old mcdonald -> Old Mcdonald*

*(Old McDonald would be find too, but I don't expect it to be THAT smart.)

A quick look at the Java String Documentation reveals only toUpperCase() and toLowerCase(), which of course do not provide the desired behavior. Naturally, Google results are dominated by those two functions. It seems like a wheel that must have been invented already, so it couldn't hurt to ask so I can use it in the future.
