How To Read A Specific Part Of A Line In Python? New update

To read a specific part of a line in Python, you can use string slicing or string manipulation methods.

String slicing allows you to extract a substring from a given string by specifying the start and end positions. For example, to extract a specific part of a line based on the character position, you can use the following syntax:

python
line = "Hello, world!"
substring = line[start_position:end_position]

Here, start_position and end_position represent the starting and ending positions of the substring you want to extract, respectively. Note that the character at the end_position index is not included in the substring.

For example, to extract the word “world” from the above line, you can use:

python
line = "Hello, world!"
substring = line[7:12]
print(substring)   # Output: world

Alternatively, you can use string manipulation methods such as split() or find() to extract a specific part of a line based on a delimiter or a specific string. For example, to extract the word “world” from the above line using the split() method, you can use:

python
line = "Hello, world!"
words = line.split(",")
substring = words[1].strip()
print(substring)   # Output: world

Here, the split(",") method splits the line into a list of words based on the delimiter “,”. The strip() method removes any leading or trailing whitespace characters from the extracted substring. Finally, the words[1] index is used to access the second word in the list, which corresponds to the “world” substring.
