Given a string str1 and we have to count the total numbers of uppercase and lowercase letters.

給定字符串str1 ，我們必須計算大寫和小寫字母的總數(shù)。

Example:

例：

Input: "Hello World!"Output:Uppercase letters: 2Lowercase letters: 8Input: "[email?protected]"Output:Uppercase letters: 1Lowercase letters: 4

Method 1:

方法1：

(Manual) By checking each character of the string with a range of uppercase and lowercase letters using the conditional statement.

(手動)通過使用條件語句檢查字符串中每個字符的大小寫范圍。

print("Input a string: ") str1 = input()no_of_ucase, no_of_lcase = 0,0for c in str1:if c>='A' and c<='Z':no_of_ucase += 1if c>='a' and c<='z':no_of_lcase += 1print("Input string is: ", str1) print("Total number of uppercase letters: ", no_of_ucase) print("Total number of lowercase letters: ", no_of_lcase)

Output

輸出量

RUN 1: Input a string: Hello World! Input string is: Hello World! Total number of uppercase letters: 2 Total number of lowercase letters: 8RUN 2: nput a string: [email?protected] Input string is: [email?protected] Total number of uppercase letters: 1 Total number of lowercase letters: 4

Method 2:

方法2：

By using islower() and isupper() methods

通過使用islower()和isupper()方法

print("Input a string: ") str1 = input()no_of_ucase, no_of_lcase = 0,0for c in str1:no_of_ucase += c.isupper()no_of_lcase += c.islower()print("Input string is: ", str1) print("Total number of uppercase letters: ", no_of_ucase) print("Total number of lowercase letters: ", no_of_lcase)

Output

輸出量

RUN 1: Input a string: Hello World! Input string is: Hello World! Total number of uppercase letters: 2 Total number of lowercase letters: 8RUN 2: nput a string: [email?protected] Input string is: [email?protected] Total number of uppercase letters: 1 Total number of lowercase letters: 4
