How to format bytes to human readable Size in Python
To format bytes to human readable Size in Python you can use the following snippet.
Sample Python
fileSize = 12454162221
for count in ['Bytes','KB','MB','GB']:
if fileSize > -1024.0 and fileSize < 1024.0:
print "%3.1f%s" % (fileSize, count)
fileSize /= 1024.0
print "%3.1f%s" % (fileSize, 'TB')
How to style a link by filetype in CSS
To style a link by filetype in CSS you can use the following snippet.
Sample CSS

How to format bytes to human readable Size in Javascript
To format bytes to human readable Size in Javascript you can use the following snippet.
Sample Javascript
function BytesToHumanReadableSize(bytes){
if(!bytes) {return '0 bytes';}
var sizeUnits = ['bytes','KB','MB','GB','TB','PB','EB','ZB','YB'];
var calc = Math.floor( Math.log(bytes) / Math.log(1024) );
calc = Math.min( Math.max(0,calc), sizeUnits.length-1);
var bytesNew = Math.round((bytes/ Math.pow(1024,calc))*100)/100;
return bytesNew + ' ' + sizeUnits[calc];
}
How to capitalize a string in Python
To capitalize a string in Python you can use the following snippet.
Sample Python
myPhrase = "HEllo wOrld!";
myPhrase = myPhrase.lower();
capChars = []
for word in myPhrase.split(' '):
if len(word) > 1:
capChars.append(word[0].upper() + word[1:])
else:
capChars.append(word.upper())
capChars = ' '.join(capChars)
print capChars;
Output:
Hello World!
another much simpler approach posted by Gomokoo on Twitter would be
print "HEllo wOrld!".lower().title();
Output:
Hello World!
How to format bytes to human readable file size in C# and VB.NET
To format bytes to human readable file size you can use the following code snippet.
Sample C#
public static String FormatToHumanReadableFileSize(object value)
{
try
{
string[] suffixNames = { "bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB" };
var counter = 0;
decimal dValue = 0;
Decimal.TryParse(value.ToString(), out dValue);
while (Math.Round(dValue / 1024) >= 1)
{
dValue /= 1024;
counter++;
}
return string.Format("{0:n1} {1}", dValue, suffixNames[counter]);
}
catch(Exception ex)
{
//catch and handle the exception
return string.Empty;
}
}
Sample VB.NET
Public Shared Function FormatToHumanReadableFileSize(value As Object) As [String]
Try
Dim suffixNames As String() = {"bytes", "KB", "MB", "GB", "TB", "PB", _
"EB", "ZB", "YB"}
Dim counter = 0
Dim dValue As Decimal = 0
Decimal.TryParse(value.ToString(), dValue)
While Math.Round(dValue / 1024) >= 1
dValue /= 1024
counter += 1
End While
Return String.Format("{0:n1} {1}", dValue, suffixNames(counter))
