python计算数组中出现的所有元素并统计出现次数

#从文本中获取，并且统计
import matplotlib.pyplot as plt
import numpy as np


f = open('TXT/123.txt')
lines = f.readlines()
data = []

for line in lines:
    data.append(int(line))
data = sorted(data)
print(data)

unique_data = np.unique(data)
print(unique_data)

resdata = []
for ii in unique_data:
    resdata.append(data.count(ii))
print(resdata)

fig = plt.figure()
plt.plot(unique_data, resdata)
plt.show()

 

 

 

y = sorted(y)
print(y) 
#统计出现的元素有哪些
unique_data = np.unique(y)
print(unique_data)

#统计某个元素出现的次数
resdata = []
for ii in unique_data:
resdata.append(y.count(ii))
print(resdata)
