Matplotlib list of tuples

I need to build a bar chart from the list of tuples that I have got with key names as labels for each bar shown on the x axis, and values as heights of the bars. Here is how my input looks like:

top20 = [['Blues', 2008], ['Guadeloupe', 1894], ['Yorkshire', 1216], ['Monterrey', 1112], ['Government', 1081], ['Algeria', 972], ['Rotterdam', 920], ['Sardinia', 913], ['Mac OS', 864], ['Coffee', 858], ['Netherlands', 849], ['Oklahoma', 829], ['Tokyo', 817], ['Boating', 801], ['Finland', 765], ['Michigan', 737], ['Tamaulipas', 733], ['Croatia', 722], ['Kagoshima', 701], ['Isuzu', 678]]

Here is the code I am currently using:

plt.bar[range[len[top20]], top20.values[], align='center'] plt.xticks[range[len[top20]], list[top20.keys[]]] plt.show[]

I know, the logic follows a dictionary as an input, but I cannot think of a way to make this work. Please help, and thank you in advance.

You can convert your tupple list into list and use that:

plt.bar[range[len[top20]], [val[1] for val in top20], align='center'] plt.xticks[range[len[top20]], [val[0] for val in top20]] plt.xticks[rotation=70] plt.show[]

output: if you remove align='center' that is:

Update: [OP asked in comments]

how would I add value labels to each bar to make the chart more comprehensive?

x_labels = [val[0] for val in top20] y_labels = [val[1] for val in top20] plt.figure[figsize=[12, 6]] ax = pd.Series[y_labels].plot[kind='bar'] ax.set_xticklabels[x_labels] rects = ax.patches for rect, label in zip[rects, y_labels]: height = rect.get_height[] ax.text[rect.get_x[] + rect.get_width[]/2, height + 5, label, ha='center', va='bottom']

output:

Also

dict[top20]

output:

{'Algeria': 972, 'Blues': 2008, 'Boating': 801, 'Coffee': 858, 'Croatia': 722, 'Finland': 765, 'Government': 1081, 'Guadeloupe': 1894, 'Isuzu': 678, 'Kagoshima': 701, 'Mac OS': 864, 'Michigan': 737, 'Monterrey': 1112, 'Netherlands': 849, 'Oklahoma': 829, 'Rotterdam': 920, 'Sardinia': 913, 'Tamaulipas': 733, 'Tokyo': 817, 'Yorkshire': 1216}

will directly convert your tupple list to dictionary.
