python:'int' object is not iterable?

Question

I try matplotlib(Chinese remainder theorem)

The Chinese Remainder Theorem (Solved Example 1) https://youtu.be/e8DtzQkjOMQ

①I want error clear: I want intersection : enumerate(list(set(dataA)&set(dataB)&set(dataC))) OK!

②I want display dataA-->X=2(mod 3)

　I want display dataB-->X=3(mod 5)

　I want display dataC-->X=2(mod 7)

import pandas as pd
import matplotlib.pyplot as plt
from matplotlib import collections as mc
import seaborn as sns
myMax=200
b1,b2,b3=2,3,2
m1,m2,m3=3,5,7
dataA = list(range(b1,myMax,m1))
dataB = list(range(b2,myMax,m2))
dataC = list(range(b3,myMax,m3))
data =   [['dataA', v] for v in dataA] \
       + [['dataB', v] for v in dataB] \
       + [['dataC', v] for v in dataC]
df = pd.DataFrame(data, columns=['data', 'value'])
plt.figure(1, figsize=(8, 2.4))
ax = sns.stripplot(data=df, x='value', y='data', jitter=False, size=7)
hc = mc.LineCollection(
  [[[0, n], [i, n]] for n, i in enumerate(map(max, (dataA,dataB,dataC)))],
  colors='k', linewidths=2)
ax.add_collection(hc)
lc = mc.LineCollection(
  [[[i, 0], [i, 2]] for i in set(dataA)&set(dataB)&set(dataC)],
  colors='red', linewidths=2)
ax.add_collection(lc)
ax.set_xlabel(''); ax.set_ylabel('')
for p in ('right', 'left', 'top', 'bottom'):
  ax.spines[p].set_visible(False)
ax.tick_params(
  left=False, bottom=False, labelleft=True, labelbottom=False)

Answer 1

Usually this error refers to trying to loop a variable with a single value Ex.:

x = 1
for y in x:
 print("HELLO")
#TypeError: 'int' object is not iterable

You must search in your program or what is failing to fetch the data list or use try and except

x = 1
try:
    for  y in x:
     print("HELLO")
except TypeError as e:
    print(f"TypeError: {e}\nERROR DETECTED....ENTERING IN EXCEPTION....\n ")
    x = ['data','data','data']
    for  y in x:
     print("HELLO")
