Python string zfill() function can pad a string with“0” to a specified width. In this tutorial, we will introduce how to use it with some examples.
For example:
text = "tutorialexample.com"
output = text.zfill(30)
print(output)
lx = len(output)
print("output length:",len(output))In this example, we will pad text to 30 length with “0”
Run this code, we will see:
00000000000tutorialexample.com output length: 30
However, we also can use rjust() function to get the same result.
For example:
output = text.rjust(30,"0")
print(output)
lx = len(output)
print("output length:",len(output))
