sorting dictionary by numeric value


sorting dictionary by numeric value

around this issue I have a dict of music genres: , Use collections.Counter which is built for this purpose:
code :
import collections

# Convert values to int
tag_weight = {k: int(v) for k, v in tag_weight.items()}  
count = collections.Counter(tag_weight)

# Print the top 10
print count.most_common(10)

# Print all, from most popular to least
print count.most_common()
[('rock', 3879179), ('electronic', 2288563), ('seen live', 2097509), ('alternative', 2059313), ('indie', 1971962), ('pop', 1873806), ('female vocalists', 1557702), ('metal', 1213678), ('classic rock', 1123712), ('alternative rock', 1123488)]

Issue sorting a multi-dimensional dictionary that has non-numeric indices in Python

fixed the issue. Will look into that further As I said in the comment below the question, your table header says "BuyValue" and you are printing "Sell value". Going by the output what you expect, I think you just made a small mistake in setting the sorter function.
It should be:
code :
lambda x: my_dict[x]['market_data']['sellValue']
lambda x: my_dict[x]['market_data']['buyValue']

it fixes the issue I have the following file: , sort numerically on column one then on column two:
code :
$ sort -nk1,1 -nk2,2 file
BTA     POS      KLD
4       79.6231  5.7083918219
4       79.7011  5.7711028907
5       20.9112  4.5559494707
5       50.7354  4.2495580809
5       112.645  4.0936819092
6       18.3889  7.3631759258
6       72.8212  4.9384741047

I think the issue was by ths following , I need to sort a file with names like these: , From the man page
code :
UN1
UN4
UN5
UN12
UR1
UR21

I hope this helps . With the helpful input of @krlmlr I managed to solve the problem. As he said, the crucial part was to just edit the levels(). For anyone interested, this is the important part:
code :
  breaks <- cut(dat_interp$z, breaks = br)
  levels(breaks) <- gsub(","," - ", levels(breaks),fixed=TRUE)
  dat_interp$breaks <- breaks
  levels(dat_interp$breaks) <- as.numeric(sapply(levels(breaks), function(x){strsplit(x, "[( ]")[[1]][[2]]}))
plot.isoline <- function(data, dbr=20, n_interp=200){

  library(akima)
  library(ggplot2)
  library(fields)

  data <- read.table(file = "http://s000.tinyupload.com/download.php?file_id=90687695741432763217&t=9068769574143276321730276", header = T)

  dint <- interp(x = data$x, y = data$y, z = data$z,
                 xo = seq(min(data$x), max(data$x), length = n_interp),
                 yo = seq(min(data$y), max(data$y), length = n_interp))

  dat_interp <- data.frame(expand.grid(x=dint$x,y=dint$y), z=c(dint$z))

  br <- seq(floor(min(dat_interp$z)/dbr)*dbr, ceiling(max(dat_interp$z)/dbr)*dbr, dbr)

  breaks <- cut(dat_interp$z, breaks = br)
  levels(breaks) <- gsub(","," - ", levels(breaks),fixed=TRUE)
  dat_interp$breaks <- breaks
  levels(dat_interp$breaks) <- as.numeric(sapply(levels(breaks), function(x){strsplit(x, "[( ]")[[1]][[2]]}))

  ret <- ggplot(dat_interp) + 
    aes(x=x, y=y, z=z) +
    geom_tile(aes(fill=breaks)) +
    scale_fill_manual("TEMP", values=tim.colors(length(br)), guide = guide_legend(reverse=TRUE)) +
    stat_contour(breaks=br) +
    scale_x_continuous(expand=c(0,0)) +
    scale_y_continuous(expand=c(0,0))

  return(ret)        
}
