## Pandas: DataFrame Exercise-80 with Solution

Write a Pandas program to check for inequality of two given DataFrames.

Sample Solution :

Python Code :

``````import pandas as pd
df1 = pd.DataFrame({'W':[68,75,86,80,None],'X':[78,85,None,80,86], 'Y':[84,94,89,83,86],'Z':[86,97,96,72,83]});
df2 = pd.DataFrame({'W':[78,75,86,80,None],'X':[78,85,96,80,76], 'Y':[84,84,89,83,86],'Z':[86,97,96,72,83]});
print("Original DataFrames:")
print(df1)
print(df2)
print("\nCheck for inequality of the said dataframes:")
print(df1.ne(df2))
``````

Sample Output:

```Original DataFrames:
W     X   Y   Z
0  68.0  78.0  84  86
1  75.0  85.0  94  97
2  86.0   NaN  89  96
3  80.0  80.0  83  72
4   NaN  86.0  86  83
W   X   Y   Z
0  78.0  78  84  86
1  75.0  85  84  97
2  86.0  96  89  96
3  80.0  80  83  72
4   NaN  76  86  83

Check for inequality of the said dataframes:
W      X      Y      Z
0   True  False  False  False
1  False  False   True  False
2  False   True  False  False
3  False  False  False  False
4   True   True  False  False
```

## Python: Tips of the Day

Join Strings in an Iterable:

```>>> words = ('Hello', 'Python', 'Programmers')
>>> '!'.join(words)
'Hello!Python!Programmers'
>>> words_dict = {0: 'zero', 1: 'one', 2: 'two', 3: 'three'}
>>> '&'.join(words_dict.values())
'zero&one&two&three'
```
