Python字符串| ascii_lowercase
在 Python3 中, ascii_lowercase
是一个预初始化的字符串,用作字符串常量。在Python中,字符串ascii_lowercase
将给出小写字母“abcdefghijklmnopqrstuvwxyz”。
Syntax : string.ascii_lowercase
Parameters : Doesn’t take any parameter, since it’s not a function.
Returns : Return all lowercase letters.
注意:确保导入字符串库函数以使用 ascii_lowercase。
代码#1:
# import string library function
import string
# Storing the value in variable result
result = string.ascii_lowercase
# Printing the value
print(result)
输出 :
abcdefghijklmnopqrstuvwxyz
代码 #2:给定代码检查字符串输入是否只有较低的 ASCII字符。
# importing string library function
import string
# Function checks if input string
# has lower only ascii letters or not
def check(value):
for letter in value:
# If anything other than lower ascii
# letter is present, then return
# False, else return True
if letter not in string.ascii_lowercase:
return False
return True
# Driver Code
input1 = "GeeksForGeeks"
print(input1, "--> ", check(input1))
input2 = "geeks for geeks"
print(input2, "--> ", check(input2))
input3 = "geeksforgeeks"
print(input3, "--> ", check(input3))
输出:
GeeksForGeeks --> False
geeks for geeks --> False
geeksforgeeks --> True
应用:
字符串常量ascii_lowercase
可以在很多实际应用中使用。让我们看一段代码,解释如何使用ascii_lowercase
生成给定大小的强随机密码。
# Importing random to generate
# random string sequence
import random
# Importing string library function
import string
def rand_pass(size):
# Takes random choices from
# ascii_letters and digits
generate_pass = ''.join([random.choice(
string.ascii_lowercase + string.digits)
for n in range(size)])
return generate_pass
# Driver Code
password = rand_pass(10)
print(password)
输出:
52v3bdyk63
