In Python Pandas(Course Id:- 55937), There are 8 Hands-On Questions Available. The Solutions are

### #### Code:-

import pandas as pd
import numpy as np
heights_A = pd.Series([176.2,158.4,167.6,156.2,161.4])
heights_A.index = ['s1','s2','s3','s4','s5']
print(heights_A.shape)

weights_A = pd.Series([85.1,90.2,76.8,80.4,78.9])
weights_A.index = ['s1','s2','s3','s4','s5']
print(weights_A.dtype)

df_A = pd.DataFrame()
df_A['Student_height'] = heights_A
df_A['Student_weight'] = weights_A
print(df_A.shape)

my_mean = 170.0
my_std = 25.0
np.random.seed(100)
heights_B = pd.Series(np.random.normal(loc = my_mean, scale = my_std, size = 5))
heights_B.index = ['s1','s2','s3','s4','s5']

my_mean1 = 75.0
my_std1 = 12.0
weights_B = pd.Series(np.random.normal(loc = my_mean1,scale = my_std1,size = 5))
weights_B.index = ['s1','s2','s3','s4','s5']

1. 1. Bro data merging 1 executed for u now

2. Numpy hands-on answers kooda pettu bro :)

3. can anyone put hands on numpy also for fresco play!! plz

4. machine learning handson also upload bro

5. Hi , I am unable to clear Accessing Pandas Data Structures - Python Pandas, it's just saying not passed validation in tasks,5,6 it has asked to use .loc or.iloc as well. I have used that too.can you help

6. Data Merging Handson-2 is getting executed correctly in Hackerank but in fresco results are not updated.

1. Can you please tell me how to solve , I'm also facing same issue

7. Can you please provide hands on for node.js essential fron fresco
