lowercase

>>> import string >>> word = "hello." >>> word2 = word.replace(string.lowercase, '.') >>> print word2 hello. I just want all the lowercase letters to turn into full stops. What am I doing wrong here? Use a regular expression : from re import sub print sub("[a-z]", '.', "hello.") str.replace is looking for the string abcdefghijklmnopqrstuvwxyz to replace it with . , not looking for each individual letter to replace. you should use string.translate() : >>> import string >>> input = 'abcABCaAbBcC' >>> input.translate(string.maketrans(string.lowercase, '.'*26)) '...ABC.A.B.C' the string.maketrans(

I'm working with the Titanic dataset available from Kaggle. I have it in a dataframe and i want to change the case of the "sex" column to lowercase. I'm using the following code import pandas as pd df = pd.read_csv('titanic.csv') print dfFull['sex'].unique() df.sex.str.lower() #check if it worked print df['sex'].unique() and also trying df['sex'].str.lower() but when I run df['sex'].unique() I get three unique values [male, female, Female] . Why does my code not lower the case of the strings and save it back to the dataframe so i get [male, female] of from the .unique method? str.lower() does

I was wondering if theres a realy good (performant) solution how to Convert a whole file to lower Case in C. I use fgetc convert the char to lower case and write it in another temp-file with fputc. At the end i remove the original and rename the tempfile to the old originals name. But i think there must be a better Solution for it. If you're processing big files (big as in, say, multi-megabytes) and this operation is absolutely speed-critical, then it might make sense to go beyond what you've inquired about. One thing to consider in particular is that a character-by-character operation will

I have an XML like <emps> <emp id='3432'> <fname>Jack</fname> <lname>Dawson</lname> <emp> <emp id='1122'> <fname>Jack</fname> <lname>Thompson</lname> <emp> <emps> I am developing a web application which searches this xml based on the first name entered and comes up with a resultant page. To achieve this I have written an xslt to transform the XML to HTML based on the input search string which is passed as a variable named srchStr. <xsl:template match="employees"> <xsl:for-each select="emp[fname=$srchStr]"> <tr> <xsl:variable name="id"> <xsl:value-of select="@id" /> </xsl:variable> <td> <a href

i would like to know if it's possible check if one letter of a string is capitalized. Other way to see it, if all letters in the string are uppercase or lowercase. Example: string a = "aaaaAaa"; string b = "AAAAAa"; if(??){ //Cheking if all the string is lowercase cout << "The string a contain a uppercase letter" << endl; } if(??){ //Checking if all the string is uppercase cout << "The string b contain a lowercase letter" << endl; } you can use standard algorithm std::all_of if( std::all_of( str.begin(), str.end(), islower ) { // all lowercase } Use all_of in concert with isupper and islower :

I'm looking at VBA code that takes an entire range of cells and converts them into lowercase. I found the following: [A1:A20] = [index(lower(A1:A20),)] This works fine for a fixed range (don't entirely understand syntax, but found the following post:) Post detailing code above My problem is this: I would like to be able to set the range dynamically as I'm dealing with changing range sizes. However, the following doesn't work, and I can't seem to be able to use INDIRECT() either in VBA. Range("A1:A" & n) = [index(lower(Range("A1:A" & n)),)] Is there a way to make this work? I would really like
