I am storing numbers in a database with a string like 5,55,15,17,2,35 I want to remove say number 5 from the string, keeping the comma seperation set like it is.

问题 I wrote a quick script to remove the 'http://' substring from a list of website addresses saved on an excel column. The function replace though, doesn't work and I don't understand why. from openpyxl import load_workbook def rem(string): print string.startswith("http://") #it yields "True" string.replace("http://","") print string, type(string) #checking if it works (it doesn't though, the output is the same as the input) wb = load_workbook("prova.xlsx") ws = wb["Sheet"] for n in xrange(2,698

问题 I want to perform arithmetic operations on numbers in a string. For example: SGJKR67 should become SGJKR68 . Another one: NYSC34 should become NYSC35 . Only numbers are changed, in this example both are increased by one. 回答1: Using regex and Capturing Groups can solve your problem: $reg = [regex]::new("([A-Z]+)(\d+)") $m = $reg.Match("SGJKR67") $digits = $m.Groups[2] # will be 67 $digits = $digit + 1; # or apply anything you want $result = "$($m.Groups[1])$digits" # will be SGJKR and 68. You

问题 If I have a multi line string like this is a line this is another line what is the best way to remove the empty line? I could make it work by splitting, iterating, and doing a condition check, but is there a better way? 回答1: Assumming that you want to have the same string with empty lines removed as an output, I would use regular expressions: import ( "fmt" "regexp" ) func main() { var s = `line 1 line 2 line 3` regex, err := regexp.Compile("\n\n") if err != nil { return } s = regex
