str.expandtabs(tabsize=8)

Parameters

  • tabsize -- Specifies the number of spaces to convert tab symbols ('\t') in the string to.

Example

The following example demonstrates the expandtabs() method:

Example

#!/usr/bin/python
# -*- coding: UTF-8 -*-

str = "example\t12345\tabc"
print('Original string: {}'.format(str))

# Default 8 spaces
# runnob has 6 characters, so the following \t is padded with 2 spaces
# 12345 has 5 characters, so the following \t is padded with 3 spaces
print('Replace\\t symbol: {}'.format(str.expandtabs()))

# 2 spaces
# runnob has 6 characters, exactly 3 times 2, so the following \t is padded with 2 spaces
# 12345 has 5 characters, not a multiple of 2, so the following \t is padded with 1 space
print('Using 2 spaces to replace\\t symbol: {}'.format(str.expandtabs(2)))

# 3 spaces
print('Using 3 spaces: {}'.format(str.expandtabs(3)))

# 4 spaces
print('Using 4 spaces: {}'.format(str.expandtabs(4)))

# 5 spaces
print('Using 5 spaces: {}'.format(str.expandtabs(5)))

# 6 spaces
print('Using 6 spaces: {}'.format(str.expandtabs(6)))

The output of the above example is as follows:

原始字符串: example      12345   abc
替换 \t 符号: example  12345   abc
使用 2 个空格替换 \t 符号: example  12345 abc
使用 3 个空格: example   12345 abc
使用 4 个空格: example  12345   abc
使用 5 个空格: example    12345     abc
使用 6 个空格: example      12345 abc
