Python | Check element for range occurrence
• Last Updated : 18 Oct, 2019

Sometimes, while working with data, we can have a simple problem in which we have ranges in form of tuple, and we need to check if a specific number lies between any of ranges suggested by tuple. This has it’s application in competitive programming. Let’s discuss certain ways in which this task can be performed.

Method #1 : Using loop + `enumerate()`
This task can be performed using combination of above functions. In this, we just need to iterate through each element of list and return the index of tuple pair between which the element exists using `enumerate()`.

 `# Python3 code to demonstrate working of``# Check element for range occurrence``# Using loop + enumerate()`` ` `# Initializing list``test_list ``=` `[(``45``, ``90``), (``100``, ``147``), (``150``, ``200``)]`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# Initializing element``N ``=` `124`` ` `# Check element for range occurrence``# Using loop + enumerate()``res ``=` `None``for` `idx ``in` `(idx ``for` `idx, (sec, fir) ``in` `enumerate``(test_list) ``if` `sec <``=` `N <``=` `fir):``    ``res ``=` `idx``     ` `# printing result``print``(``"The index of tuple between which element occurs : "` `+` `str``(res))`
Output :
```The original list is : [(45, 90), (100, 147), (150, 200)]
The index of tuple between which element occurs : 1
```

Method #2 : Using `next() + enumerate()` + generator expression
This task can also be performed using combination of above functions. In this, we just iterate through using `next()`. Rest everything is performed similar to the above function.

 `# Python3 code to demonstrate working of``# Check element for range occurrence``# Using next() + enumerate() + generator expression`` ` `# Initializing list``test_list ``=` `[(``45``, ``90``), (``100``, ``147``), (``150``, ``200``)]`` ` `# printing original list``print``(``"The original list is : "` `+` `str``(test_list))`` ` `# Initializing element``N ``=` `124`` ` `# Check element for range occurrence``# Using next() + enumerate() + generator expression``res ``=` `next``((idx ``for` `idx, (sec, fir) ``in` `enumerate``(test_list) ``if` `sec <``=` `N <``=` `fir), ``None``)``     ` `# printing result``print``(``"The index of tuple between which element occurs : "` `+` `str``(res))`
Output :
```The original list is : [(45, 90), (100, 147), (150, 200)]
The index of tuple between which element occurs : 1
```
