The write method places one string into an open file object. The string may contain several lines, but write adds no newline automatically; include \n when the output needs one. section 13.4
Use these rules when writing text:
- Text mode can translate \n into platform-specific line endings. Pass newline="\n", newline="\r", or newline="\r\n" to force a particular representation. section 13.4
- Binary mode returns and processes bytes without newline translation, so the newline parameter is unnecessary. section 13.4 section 13.11
- Use writelines for a sequence of strings, but remember that it also inserts no newlines; strings without \n are concatenated. section 13.4
- The same write and writelines methods work on specialized standard-output and standard-error file objects. section 13.6
Writing multiple lines
myfile.write("Hello\nWorld\nHow are you?") This writes three lines because the string supplies the newline characters explicitly. A write call returns the number of characters written; for standard output, the displayed count is 30 in the shown example. section 13.4 section 13.6
myfile.write("Hello\nWorld\nHow are you?")
Inspect the compact listing showing a single write call with embedded newline characters. section 13.4
