# Python: Check common elements between two given list are in same order or not

## Python List: Exercise - 133 with Solution

Write a Python program to check if two lists have the same elements in them in same order or not.

Sample Solution:

Python Code:

``````def same_order(l1, l2):
common_elements = set(l1) & set(l2)
l1 = [e for e in l1 if e in common_elements]
l2 = [e for e in l2 if e in common_elements]
return l1 == l2

color1 = ["red","green","black","orange"]
color2 = ["red","pink","green","white","black"]
color3 = ["white","orange","pink","black"]

print("Original lists:")
print(color1)
print(color2)
print(color3)
print("\nTest common elements between color1 and color2 are in same order?")
print(same_order(color1, color2))
print("\nTest common elements between color1 and color3 are in same order?")
print(same_order(color1, color3))
print("\nTest common elements between color2 and color3 are in same order?")
print(same_order(color2, color3))
```
```

Sample Output:

```Original lists:
['red', 'green', 'black', 'orange']
['red', 'pink', 'green', 'white', 'black']
['white', 'orange', 'pink', 'black']

Test common elements between color1 and color2 are in same order?
True

Test common elements between color1 and color3 are in same order?
False

Test common elements between color2 and color3 are in same order?
False
```

## Python: Tips of the Day

Decapitalizes the first letter of a string:

Example:

```def tips_decapitalize(s, upper_rest=False):
return s[:1].lower() + (s[1:].upper() if upper_rest else s[1:])
print(tips_decapitalize('PythonTips'))
print(tips_decapitalize('PythonTips', True))
```

Output:

```pythonTips
pYTHONTIPS
```
