List in Python:

Lists in Python are mutable sequences. They are extremely similar to tuples, except they do not have immutability constraints. Lists are often used to store collections of homogeneous things, but there is nothing stopping you from storing collections of heterogeneous items as well.

List clear() Method in Python:

The clear() method clears or removes all the elements from the list.

Syntax:

list.clear()

Parameter Values: This method has no parameters.

Return Value:

The clear() method only removes items from the specified list. It doesn’t return anything.

Examples:

Example1:

Input:

Given list = ["good", "morning", "btechgeeks"]

Output:

The given list is : ['good', 'morning', 'btechgeeks']
The given list after applying clear() method: []

Example2:

Python String isnumeric() Method with Examples

Python / By

In the previous article, we have discussed Python Program for help() Function with Examples
isnumeric() Method in Python:

If all of the characters are numeric (0-9), the isnumeric() method returns True; otherwise, it returns False.

Exponents such as ² and ¾ are also considered numeric values.

Because all of the characters in the string must be numeric, “-2” and “1.4” are NOT considered numeric values.

And the ‘-‘, ‘.’ are not the numeric values.

Numeric characters in Python include decimal characters (such as 0, 1, 2..), digits (such as subscript, superscript), and characters with the Unicode numeric value property (such as fractions, roman numerals, currency numerators).

Syntax:

string.isnumeric()

Parameters: This function has no parameters.

Return Value:

The isnumeric() method gives:

  • True if all of the characters in the string are numbers.
  • If at least one of the characters is not a numeric character, the statement is false.

Examples:

Example1:

Input:

Given string = '-6'
Given string = '5/6'
Given string = 'btechgeeks 12345'

Output:

The given string =  -6
Checking if the given string has all numeric characters or not =  False
The given string =  5/6
Checking if the given string has all numeric characters or not =  False
The given string =  btechgeeks 12345
Checking if the given string has all numeric characters or not =  False

Example2:

Input:

Given string = '\u0030'
Given string = '1.7'
Given string = '\u00B2'

Output:

The given string = 0
Checking if the given string has all numeric characters or not = True

Python String zfill() Method with Examples

Python / By

In the previous article, we have discussed Python String splitlines() Method with Examples
zfill() Method in Python:

The zfill() method appends zeros (0) to the beginning of a string until it reaches the specified length.

If the len parameter value is less than the length of the string, no filling is performed.

Syntax:

string.zfill(len)

Parameters

len: This is Required. A number indicating the string’s desired length.

Return Value:

zfill() returns a copy of the string with 0 to the left filled in. The length of the returned string is determined by the width specified.

  • Assume the string’s initial length is 10. Furthermore, the width is specified as 15. zfill() returns a copy of the string with five ‘0’ digits filled to the left in this case.
  • Assume the string’s initial length is 10. In addition, the width is specified as 8. In this case, zfill() returns a copy of the original string rather than filling ‘0’ digits to the left. In this case, the length of the returned string will be 10.

Examples:

Example1:

Input:

Given string = "hello btechgeeks"
Given number = 10

Output:

hello btechgeeks

Example2:

Input:

Given string = "hello btechgeeks"
Given number = 25
