In Python, there are often line breaks when outputting content, and in some cases, we need to get rid of line breaks, so how do we get rid of line breaks in Python? There are a variety of methods that can be used, so let's take a look.
1. Use the strip() function
The strip() function is a built-in function in Python that removes characters such as spaces and newlines from the beginning and end of strings. Using this function, we can easily remove line breaks from strings. For example:
str="hello world"
str=str.strip('')
print(str)
Output: hello world
2. Use the replace() function
The replace() function can be used to replace the specified string with another string. We can use this function to remove the line break in the string, i.e. replace it with an empty string. For example:
str="hello world"
str=str.replace('',")
print(str)
Output: hello world
3. Use the split() function
The split() function is used to split a string into a list, and the splitting criteria are specified as a delimiter. We can use the function to split the string into multiple lines and remove line breaks from it. For example:
def remove_newlines(input_str):
lines=input_str.split('')
new_lines=
for line in lines:
if line.strip():
new_lines.append(line)
return",join(new_lines)
4. Use regular expressions
Regular expressions are a language used to match patterns in strings. We can use regular expressions to remove line breaks from strings. For example:
import re
str="hello world"
str=re.sub('',",str)
print(str)
Output: hello world
