[英]Diffing order of two python lists visually?
我有兩個列表,它們具有相同的元素但順序不同。
foo = ["A", "B", "C", "D", "E", "F"]
bar = ["C", "A", "B", "D", "E", "F"]
現在,我想知道哪些元素被交換並呈現在情節中,並提供一些視覺線索,以便更容易地發現改組。
該圖應在不同元素之間使用彩色線條。 類似於下面的內容,但帶有顏色和 matplotlib。
A B C D E F
v---\---\--^
C A B D E F
首先,這將列出所有未映射到相同值的項目
for f, b, in zip(foo, bar):
if f != b:
print(f, b)
擴展 alphanimals 示例以查找位置,您可以使用 annotate 來指示數組位置,然后使用 index 來查找數組中交換的位置。
如下例所示:
import matplotlib.pyplot as plt
foo = ["A", "B", "C", "D", "E", "F"]
bar = ["C", "A", "B", "D", "E", "F"]
# put data point names on plots
for num in range(len(bar)):
plt.annotate(bar[num], # this is the text
(num,1), # this is the point to label
textcoords="offset points", # how to position the text
xytext=(0,10), # distance from text to points (x,y)
ha='center') # horizontal alignment can be left, right or center
for num in range(len(foo)):
plt.annotate(foo[num], # this is the text
(num,2), # this is the point to label
textcoords="offset points", # how to position the text
xytext=(0,10), # distance from text to points (x,y)
ha='center') # horizontal alignment can be left, right or center
plt.plot(foo,len(foo)*[1],'bo-')
plt.plot(bar,len(bar)*[2],'bo-')
for f, b, in zip(foo, bar):
if f != b:
print(f,b)
bar_position = bar.index(f)
foo_position = foo.index(f)
swappositions = [bar_position,foo_position]
plt.plot(swappositions,[1,2],'r--') # indicates dashed red line for swapped elements
#turn off ticks
plt.tick_params(
axis='x', # changes apply to the x-axis
which='both', # both major and minor ticks are affected
bottom=False, # ticks along the bottom edge are off
top=False, # ticks along the top edge are off
labelbottom=False) # labels along the bottom edge are off
plt.show()
