Python String startswith() and endswith() Guide
You can use the startswith() and endswith() methods in Python to check if a string starts or ends with a specific substring.
For example, to check if a string str starts with a substring prefix, you can use the following code:
if str.startswith(prefix):
print("字符串以特定子字符串开头")
else:
print("字符串不以特定子字符串开头")
Similarly, to check if a string “str” ends with a substring “suffix”, you can use the following code:
if str.endswith(suffix):
print("字符串以特定子字符串结尾")
else:
print("字符串不以特定子字符串结尾")
