lowercase

I'm trying to print all data from a csv in lowercase, but I'm not having any luck. Here's what I have so far: import csv books = csv.reader(open("books.csv","rb")) for row in books: print row This prints all the content of the csv, but when I add the .lower() function, I get errors. What am I doing wrong? Try print [r.lower() for r in row] 来源： https://stackoverflow.com/questions/8265648/using-the-lowercase-function-with-csv-rows

This question already has an answer here: How do I lowercase a string in C? 5 answers I have a char foo[SIZE]; //(string) and have inputed it correctly using %s (as in it printfs the correct input), but now want to set it to lowercase. So I tried using if (isupper(*foo)) *foo=tolower(*foo); ie when I do: printf("%s" foo); //I get the same text with upper case The text does not seem to change. Thank you. foo isn't a pointer, so you don't want to use it as one. You also don't have to check whether a character is an upper-case letter before using tolower -- it converts upper to lower case, and

In one of my interview, the interviewer asked me why the upper case letters are before the lower case letters in ASCII table, I searched on google.com but found nothing, could anyone gave me the answer? Thx a lot! I'm only guessing, but I imagine it's because the earliest character sets had no lowercase at all. The Baudot telegraph code was only 5 bits, and CDC mainframes natively used a 6-bit code; there was no room for lowercase. When ASCII was developed as a 7-bit code which finally had enough room for lowercase letters, they were considered something of a luxury add-on, so it made sense to

int main() { string s; cout << "enter the string :" << endl; cin >> s; for (int i = 0; i < s.length(); i++) s[i] ^= 32; cout << "modified string is : " << s << endl; return 0; } I saw this code which converts uppercase to lowercase on stackoverflow. But I don't understand the line s[i] = s[i]^32 . How does it work? ^= is the exclusive-or assignment operator. 32 is 100000 in binary, so ^= 32 switches the fifth bit in the destination. In ASCII, lower and upper case letters are 32 positions apart, so this converts lower to upper case, and also the other way. But it only works for ASCII, not for

I was wondering why people don't use uppercase in name of header files. I see many header files with name only in lowercase. But I thought it would be more easy to read if they write them with uppercase, say "BaseClass.h", "SubClass.h", instead of "baseclass.h", "subclass.h". Why is that? Or it's just that the header files I've seen are named only in lowercase? There are systems out there which are case-sensitive (*nix), and there are systems which are traditionally case-insensitive (Windows). As a result, if you develop on *nix and create two files: baseclass.h and BaseClass.h - your code

This question already has an answer here: How to lowercase a pandas dataframe string column if it has missing values? 8 answers I have a data that contains domain names: url var1 www.CNN.com xsd www.Nbc.com wer www.BBc.com xyz www.fOX.com zyx .... The data is of the Series type. I am using the following to convert url variable to lower case: df.apply(lambda x: x.astype(str).str.lower()) However, they remain the same. What am I doing wrong? df['url'] = df['url'].str.lower() should operate on the series and replace it with the lower case version. I think you need assign output back, better is

I am wondering that why Character.toUpperCase/toLowerCase has no Locale parameter like String.toUpperCase/toLowerCase . I have to first uppercase of a text that can be in Any language. I have 2 solutions: Use Character.toUpperCase String text = "stack overflow"; StringBuilder sb = new StringBuilder(text); sb.setCharAt(0, Character.toUpperCase(sb.charAt(0))); // No Locale parameter here. String out = sb.toString(); //Out: Stack overflow Use String.toUpperCase Locale myLocale = new Locale(locateId); String text = "stack overflow"; String text1 = text.substring(0,1).toUpperCase(myLocale ); String
