# python how to split a number with code examples

Python provides a variety of ways to split a number. Here are a few examples:

1. Using the `divmod()` function:
```# Divides the number a by b and returns a tuple containing the quotient and remainder

a = 17
b = 3
print(divmod(a, b))
# Output: (5, 2)
```
1. Using the `//` operator:
```# Returns the quotient of a and b

a = 17
b = 3
print(a // b)
# Output: 5
```
1. Using the `%` operator:
```# Returns the remainder of a and b

a = 17
b = 3
print(a % b)
# Output: 2
```

You can also use these operators and functions in conjunction with each other to split a number in various ways. For example:

```# Using the divmod() function and the // operator

a = 17
b = 3
q, r = divmod(a, b)
print(q, r)
# Output: (5, 2)

# Using the // operator and the % operator

a = 17
b = 3
q = a // b
r = a % b
print(q, r)
# Output: (5, 2)
```

Additionally, you can also use the `split()` function to split a number based on a specific character or delimiter. Here is an example:

```# Splitting a number by a specific character

a = "17,3"
b = a.split(",")
print(b)
# Output: ['17', '3']
```

In this example, the number '17,3' is split by the delimiter ',' and the result is a list containing two elements '17' and '3'.

In conclusion, Python provides multiple ways to split a number, whether it be by using the `divmod()` function, the `//` and `%` operators, or the `split()` function. These methods can be used depending on the specific requirements of the task at hand.

In addition to the methods mentioned above, there are a few other ways to split a number in Python.

1. Using the `str.split()` method: This method is similar to the `split()` function, but it is used on a string object. It splits the string into a list of substrings based on a specified delimiter.
```a = "17;3"
b = a.split(";")
print(b)
# Output: ['17', '3']
```

This method can also be used to split a number that is represented as a string into a list of individual digits.

```a = "17"
b = list(a)
print(b)
# Output: ['1', '7']
```
1. Using a list comprehension: This method can be used to split a number into a list of individual digits.
```a = 17
b = [int(i) for i in str(a)]
print(b)
# Output: [1, 7]
```

This method uses a list comprehension to iterate through the string representation of the number and convert each character to an integer.

1. Using the `math.modf()` function: This function is similar to the `divmod()` function but instead of returning a tuple, it returns a pair of floats representing the fractional and integral parts of the number.
```import math
a = 17.5
b,c = math.modf(a)
print(b,c)
# Output: (0.5, 17.0)
```

In addition to these methods, it's also possible to split a number into its individual digits using bitwise operators such as `>>` and `&`. However, these methods are more advanced and not as commonly used as the methods mentioned above.

In addition, you can also use string formatting method to split number into certain format. For example:

```a = 12345
print("{:03}-{:03}-{:04}".format(a//10000, a%10000//100, a%100))
# Output: '012-345-67'
```

In conclusion, Python provides a variety of ways to split a number, whether it be by using the `divmod()` function, the `//` and `%` operators, the `split()` function, list comprehension, `math.modf()` function, bitwise operator and string formatting. Each method has its own use case, and the choice of method will depend on the specific requirements of the task at hand.

## Popular questions

1. What is the divmod() function in Python and how is it used to split a number?

The `divmod()` function in Python is used to divide a number by another number and return a tuple containing the quotient and remainder of the division. For example:

```a = 17
b = 3
print(divmod(a, b))
# Output: (5, 2)
```
1. How can the // and % operators be used to split a number in Python?

The `//` operator in Python is used to return the quotient of a division, while the `%` operator is used to return the remainder. For example:

```a = 17
b = 3
q = a // b
r = a % b
print(q, r)
# Output: (5, 2)
```
1. How can the split() function be used to split a number in Python?

The `split()` function in Python can be used to split a string into a list of substrings based on a specified delimiter. For example:

```a = "17,3"
b = a.split(",")
print(b)
# Output: ['17', '3']
```
1. How can a list comprehension be used to split a number in Python?

A list comprehension can be used to split a number into a list of individual digits. For example:

```a = 17
b = [int(i) for i in str(a)]
print(b)
# Output: [1, 7]
```
1. What is the modf() function in python and how it can be used to split a number?

The `math.modf()` function in python is used to return the fractional and integral parts of a number as a pair of floats. For example:

```import math
a = 17.5
b,c = math.modf(a)
print(b,c)
# Output: (0.5, 17.0)
```

It can be used to split a float number into its integral and fractional parts.
